It seems to me that every night one see a different set of stars because of Earth orbit. As I figure if I am correct that the night view of Earth point outwardly away from the Sun all around through four seasons. What you see during wintertime is exactly opposite to what you see during summertime as well as fall and spring. I also find it interesting that a circle consists of 360 degrees similar to number of days in a year (365), so every night one will see one half degree disappear while another half degree appears in the whole sky set of stars.

For any concerned with light pollution that makes too many stars disappear before one's own naked eyes, even though telescopes can still help one spot the disappeared stars, there is online maps that shows where the light pollution are and are not . For most metropolitian centers, one probably needs to drive at least 50 miles out of the centers to enjoy the lowest brackets of light pollution. All u need to do is to google "light pollution" and you will come up with nice list of links to different light pollution information including maps , etc. it is educational.

I am posting a message here as an impatient astronomer without knowledge about the sky whatsoever, yet bought a decent telescope that cost only $315 or so. it is BRESSER AR102S Comet Edition that can be bought online . it is a very good beginner telescope because of doublet objective lens that gives crisp viewing with 20mm EP included. For around $45, you can order 10mm EP that will give you 46x magnifaction . Stars are crispy and colorful to one's own delight. it is as basic as it gets as one can aim anywhere frequently without too much fuss . I am surprised that it is not catching on among the beginners who are needlessly fancied with the cheap computerized smaller objective telescopes. I wouldn't settle for anything smaller than 100mm objective refractor types.. I am satisfied with it.

What are influences that make google sky maps unreliable... This I say because when I put my phone on my right sight the moon and Pluto appear. nice! but even so when I hold my phone on my left. Both outward looking off course
4/11/2015 3:48:11 AM

This is a lovely sky-map. North is shown as at the top, while South is shown at the bottom. Why is East shown at the left, and West shown at the right sides of the sky-map?
I ask this because if you stand facing North, the West is always on your left, and the East is always on your right. Why should it be any different on this sky-map, if the view is facing towards the North?
Shouldn't it show West on the left side, and East on the right side?

I have SkyMap on my Windows phone it is superb, though my phone does not have a compass. I have just bought android tablet and cannot find an app that is anything like as good. Will you be bringing out a version for android, please!

Great sky map! It also runs on my Mac, which is nice. However, there it is drawn on a pitch black background, supposedly to imitate night sky. And giving good readability to the sky objects. But looking at instructions they are white on black background which makes the dark blue highlighted links etc unreadable. Is there a possibility to select other color?

Greeting Ciprian,

Thank you for this great online tool. With your permission, I'd like to include a screen grab of your sky chart over Hopkinsville at August 21, 2017 18:24 GMT, in a book I'm preparing to promote the August 21, 2017 Solar Eclipse.

I will of course attribute the map courtesy of May I have your permission? This is part of our effort to promote interest in the August 21, 2017 Solar Eclipse and in Astronomy.

You can contact me at eclipse

Thank you,

Just found SkyMap...looks interesting.
However, when I align my view to North and South, East and West are reversed.
I am in the Southern hemisphere...using the Brisbane, Australia location.
I am an old bloke and not science educated.
What am I doing wrong?

Installed on win 8.1 laptop no touch screen. No toolbars, no zoom? How do I zoom out. Same features as free no additional features with paid version.

Please advise.

i have an Android phone, downloaded Skymap , does it need a compass in the phone or does it work with the help of the camera only ??
10/4/2014 3:17:00 PM

@Jon - The apps on windows phone and windows RT/ windows 8 are similar. The windows phone has a bit more features, while on a tablet you have a bigger screen. But, according to our experience, the phones have better sensors (compass and accelerometer).
Our apps have trial versions and free version and you can install them for free before deciding to buy or not.
9/23/2014 9:57:50 AM


I purchased your app for Windows Phone 8.1 and just recently bought a windows RT device. I was wondering if the app for Windows RT has any significant features that would make me buy it again for another device.


9/22/2014 10:35:18 AM

@all - A few users complained about the recent changes. While they made the site look a little bit better, I agree that these changes didn't improve the functionality. Therefore, I've decided to revert back to the old menu and controls. I plan to get an improved functionality anyway in the future, and get a real functional HTML5 page (better map manipulation, better controls and menus, etc)

This site now shows distances to the stars in HIP catalog (over 100 thousand stars).
9/13/2014 2:09:11 PM

@michelle - you have to use the compass control (the little N nob), located to the left of the map in order to "rotate" the map in the direction you're looking at; we can see Ursa Major (Big Dipper) usually facing North and, by default what you see on this site without changing the config, is the sky as you can see facing South.
Click on the little circle around the compass control in order to change the direction of the map.

Hello, I want to translate your sky maps into Vietnamese. Can you accept my requst. If you accept, you can send me information to my email address. Thank you !
9/6/2014 7:33:59 PM

Hi, my question is why is my map slightly off the mark, also the plough/big dipper is the wro g way around?
8/31/2014 2:19:38 PM

@all - I may rewrite the menu and date/time change based on users feedback. I'm also planning to write code to take advantage of GPU for HTML5 version of the map and get improved graphics as a result. Only if I had enough time for all these plans...
8/29/2014 7:41:26 PM

@Jan - you can click on the small circle around the compass image (on the left side of the map) in order to rotate the map to WNW or other directions.
8/29/2014 7:32:19 PM

@Victor - thanks for reporting that issue. I'll fix it. However, this sky map is accurate for the year interval 1900 - 2100 because is based on a present time star catalog.
8/29/2014 7:25:37 PM

@pico - I have no immediate plans to port SkyMap on Android... I'm not a windows phone only developer but porting the code on other platforms takes time and effort, and SkyMap, despite generating some revenue, it's not paying the bills. I have a regular job and I can't promise much.
I have ported the code on iOS in a partnership with Meade. There were discussions of porting the code on Android, but so far, I haven't done any progress.
@Usman - are you talking about SkyKey? Isn't that app working on your iPhone?
8/29/2014 7:06:11 PM

@John, we are a total of 2 developers of the windows phone app and I've personally implemented the code for "Select City" list. It's funny, nobody called me "geographically challenged" before:) Select City list came from a public domain list of cities with their corresponding GPS position. I didn't pick those cities by hand and, frankly, I was aware of Canberra being the capital city of Australia since I was a child (despite the fact that I haven't traveled yet to Australia). Now, because there's a request I'll consider adding Canberra to my list and have it there in the next release. Most app users actually take advantage of the auto-location feature.
8/29/2014 6:59:47 PM

I have just purchased SkyMap.

I find it odd that Australia's capital city, Canberra, does not get a listing in the "Select City" list.

Are the app developers "geographically challenged"?
8/29/2014 6:35:38 AM

I had this app on my Windows Nokia phone, which unfortunately died, picked up the Samsung Galaxy S5, great phone, but no app like Sky Map for it. The apps available for it are awful, cumbersome and just don't work. Any plans to develop Sky Map for android based phones?
8/16/2014 8:01:51 AM

SkyMap is not working on my iphone5, can anybody help me out???
7/23/2014 1:39:33 PM

The map breaks if you try to do any date before 01/01/1000..... That's frustrating. Can you fix that, please?
6/22/2014 4:13:21 PM

We need to e able to rotate map so as to align map north with our seated or sanding north.

For example, my window bears NNW. Need to rotate map to compensate.

Simple code.

6/19/2014 7:58:20 PM

Oops. I think I'm wrong. Never mind. I guess Saturn stays in one constellation about 2.5 years. I apologize. Looks like I'm the one who was confused. Must be too many vodka-and-orange juices last night. Sorry. Jonathan
6/7/2014 9:54:20 AM

I apologize for my multiple comments. Wikipedia's "Saturn" article says: "It takes approximately 29.5 years for the planet to complete an entire circuit of the ecliptic against the background constellations of the zodiac." I notice researching online that there is a lot of confusion on many astrology websites such that Saturn is incorrectly believed to take 28 or 30 years to complete one revolution around the Zodiac when in fact it stays in one constellation continously for about 30 years before slowly shifting to the next one. Could there be a glitch in star map programs, similar to whatever is wrong with Skymaponline, contributing to this misconception? Jonathan
6/7/2014 9:34:44 AM

Oops, I meant to say, "Sorry to inform you!" As regards changes from the old version, it used to be easier to quickly change dates/times, zoom in/out, go to print version, and back, whereas with recent changes, it seemed to get bogged down and freeze a lot, but today it seems better. However, the problem with Saturn's position is MUCH more worrisome! Jonathan
6/7/2014 8:09:23 AM

Good morning! Specificially, try June 7, 1964, 9:30 a.m., when Saturn should be in Leo, but Skymaponline shows Saturn in Aquarius, which is 180 degrees opposite on the zodiac, so there must be some MAJOR glitch in your program, so to inform you! Sincerely, Jonathan
6/7/2014 8:03:51 AM

Good morning! Something is EXTREMELY FAULTY with your program! Saturn is so slow it stays 30 years in one constellation and only recently finally shifted from Virgo into Libra. But setting the date for, e.g., 1964, and Skymaponline shows Saturn in Aquarius, which is IMPOSSIBLE! Sincerely, Jonathan
6/7/2014 7:57:20 AM

@Klat - please see my comment on 1/14/14: "a sky map is different than a regular land map; the point of reference for a sky map is our position on earth and we see the map as we look down; a regular land map has a bird eye point of reference, as the land is seen from the air by a bird"
@Jonathan - sorry you don't like the last set of changes; I may implement more changes to improve the experience but you should explain what exactly you're missing from the old version
@Mikko - the compass sensors on some tablets are not great and require calibration - please make sure you rotate the tablet on all its axis with large movements
6/6/2014 10:54:54 PM

When the direction 'NORTH' is at the top of the map...WHY then is the map direction 'WEST' on the 90 degree quadrant (3 o'clock) instead of at the CORRECT 270 degree (9 o'clock)???

Did the world's longitudes suddenly reverse or what exactly am I missing here?
6/1/2014 4:45:51 PM

Used to be more useable until stupid changes.
5/19/2014 6:23:48 PM

I just downloaded Sky Map 1.1 for Windows RT. Same great looking eye candy as on my Windows Phone, but the Point to Sky feature is pointing 180 degrees off - if I hold the tablet to the south, the view is to the north, same with east vs. west! Using a Lumia 2520.
Anybody seen this on a Surface/Surface2 tablet?

5/11/2014 9:35:51 PM

you need to add the Ecliptic line to the program. Otherwise how can users tell where the sun and planets rise and fall relative to the horizon.
4/28/2014 9:05:27 AM

It used to be much easier to change the date and time.
4/6/2014 7:27:51 AM

Sorry, the browser got a life by itself...
please delete the duplicate comments :-(
3/20/2014 8:02:13 AM

Love the app: It has been the first one I installed on my WP8 Lumia 820!

Still, being a caffeine addict, I noticed how my shaking hands affect the app usability in moderate to high zooming mode in point to sky mode.

Is it possible to add the possibility to filter high frequency modes in pointing? While this may introduce a certain degree of lag when moving fast through the sky, usability will be GREATLY improved when pointing steady in a given direction in point to sky mode.
3/20/2014 3:50:26 AM

@mike - which app are you referring to? the website, SkyMap for windows phone or SkyKey for iPhone?
I like your suggestion but I'll probably start by updating the website. It's way easier and faster to update the website.
3/10/2014 7:27:46 PM

@Sergey - time means your local computer's time. That is converted to Greenwich time and used accordingly
@Inzar and @erin - I'll consider adding satellites but may take some time; my focus now is to improve the UI and eventually add more options (I've already started by changing the location and time dialogs)
3/8/2014 10:45:37 AM

This site is crazy :)
2/27/2014 8:49:38 PM

Can you add the exact position of the northern Center pole (ncp) or/and its Pendant, the southern Center pole im your apps? This would shorten the adjusting time of a telescope. Thank you.
2/26/2014 11:18:40 AM

Inzar ul haq
can you add satlite
2/14/2014 6:59:40 AM

Good day.
Thank you for this very useful map. I would like to clarify one thing. What is meant by "time" in settings? Greenwich time? Local administrative time in the geographic point which is selected in settings? Local time of me as a user?

@Ben - sure you can print the sky map from this site.
You can use the "Printable Map" menu entry, too.
@Marek - use the "Time" menu on top of the main page - you can manage the time there
@Steve - please install the latest update - we provided app bar entry to disable the artwork due to popular request (click ... and select hide artwork)

Good day.

I am Ben Geronimo, a BS Astronomy Technology student here in the Philippines of the Rizal Technological University. I would like to ask a question. Would it be alright if I print a sky map here in your website? It will be used in our school publication for sky mapping in our country. If you would graciously permit me to do so, I would credit you and this website for the sourcing.

For feedback, I find your website very interesting and simple. It is easy to use and very convenient.

Thank you :)

I enjoy your app but I have a suggestion for the app could you add to the site when comets and meteorite showers are visible
12/28/2013 2:34:06 PM

Very.... Very good software.
"Gunpoint" icon cannot switch to "compass menu". It can switch between quick settings, and zoom bar or nothing.
My wish is, that You could add another menu to manage time. Currently it is only in zoom menu, but I can add or subtract hour, not mins and days. And instead of 90, 45, 15... degree zoom, I suggest to change + - icons with zoom at half previous zoom. Eg. currently is 90 degree, after plus it switch to 45, next plus, switch 25, next 10, next 5... 2... 1.
12/24/2013 2:43:51 AM

In the Windows Phone SkyMap app, is there a way to disable the artwork? Also, the app hasn't been updated since March 2012 - are there any plans for future development?
12/22/2013 7:23:48 PM

I never understood why map always look the wrong way for me. Yours is the same and on top of that the sky "rotates" the wrong way over time. Yours go positive (counter clock wise) while when I look at the sky at night the sky appears to rotate negatively (clock wise). How should I interpret or look at your map?
12/11/2013 4:58:56 AM

I want to save this site in my browser's favourite list, with my location saved. Is it possible?
12/7/2013 7:47:23 AM

@wow - I've implemented only the option to hide the constellation names and not star or planet names. Thanks for the suggestion. I'll consider it for implementation.
@Dani - telrad circle sizes should be 4 degrees for the outer circle, 2 degrees for the middle circle, and 1/2 degree for the circle in the center.
12/4/2013 11:01:50 AM

great site. I'm thinking to use it to determine sky positions (very dark fields needed) for technical measurements of our telescope. Therefore, I need to draw the FoV (in that case 4.5 degree diameter) - the telrad could be useful for this - however only when I know the size - what are the diameters of the different circles of the telrad?
12/4/2013 4:28:05 AM

Thank you for providing this. It's very useful to check my identifications of stars during my nighttime walks with my dog. Now that I live where pollution (light and ugly other) is minimal, I'm re-learning my way in the night sky.
12/1/2013 3:09:19 AM

This site is wonderful. Thanks so much! One question- is there any way to hide all text on the map, even the planet and star names? Thanks!
11/29/2013 4:16:54 PM

Very good app, but names fonts need to be bigger so does the planet sizes. Iam Using on the iPhone.
11/22/2013 9:33:37 AM

@oatmealface - please click on location (e.g. the default is Seattle, WA and change it to your location or some city nearby / Bidgeport, I assume). Then you can also change the time (e.g. Nob 14th, 8PM).
You'll see that the Moon is going to be visible (almost full ~ 97%) at that time and pretty high in the sky.
@anunnaki - sorry, I haven't included ISON or other comets in my map; it require extra match calculations and more important, time on my side. You see, I have a full job and I spend my time with my wife and daughter plus writing various software (phone apps, websites, etc). I was considering adding the comet in my map, but I can't make any promise.
@Joe Freaked_Out - assuming you live near San Diego and watch the sky during evenings, then the bright item is Venus (I found out that using my own map). Believe me, we can't see Venus here in Seattle because it's under the horizon.
I assume the map rotation, it's not very intuitive - I'll try to change it.
11/11/2013 11:05:07 PM

Joe Freaked_Out
Chri_st! I just wanted to know what that bright item in the southwest portion of the sky was. A planet or a star. However, I've got to become a darn astronomer to read all this stuff and I just wanted to know ONE thing. I poked around on this stupid map for a long time and I STILL don't know what it is! Make it easy for SKY DUMMIES like me. I'm a computer programmer and a pilot so I'm not ignorant... but I AM ignorant when it comes to astronomy. Not my bag!
11/11/2013 6:44:57 PM

Where is ISON ?
11/10/2013 1:19:02 PM

why is it that the ONE main object visible in the night sky can only be shown if it's visible AT THE CURRENT TIME? why can't i figure out if the stupid MOON will be visible at 8 pm on November 14th?
10/28/2013 12:28:14 PM

I like it a lot
10/26/2013 12:24:19 AM

Marilyn Dayen
Looking at your skymap, it's really great, but when you're looking or travelling north, shouldn't east be on your right and west be on your left?
You have east labeled as west, and west labeled as east on the compass points on your skymap.
10/1/2013 5:17:07 AM

@Thomas - I'm sorry but we are not the publishers of our own Windows Phone app. Microsoft is in charge of that, the app is published through their own marketplace. If you use a different user account, then you should contact Microsoft and see if they can help. I've just written you a private email on this subject...
@lucella - galaxyIII is on Android and I assume you're using a different app (not one of mine)
@Dharmvir and cliff - you should look on a sky map in a reverse way - as if you're looking above (east is on left and west to right, opposed to other way found on a regular map)
9/25/2013 5:29:05 PM

Don't know what I'm doing wrong but the moon and obvious constellations are not where I point my device. The moon is somewhere else. Not very trustworthy. Any ideas what's wrong? Using a galaxyIII.

@dave - I think you're talking about the windows phone app. Yes, you can turn the constellations artworks off there: Please click ... on the bottom right of the screen and then select settings - display - (drag up) - constellation, show art off.
@P. Johnson - yes, that's a good suggestion. I'll consider it in a future update.
7/16/2013 10:57:42 AM

@Jesse, thanks for your suggestion. I know about the ascom drivers but there are some restrictions for applications on marketplace. As a telescope owner with a passion for astro-photography, I understand quite well your request. There was not possible to be done on windows phones but, the stroy may be different on tablets.
@maryjane - we use sky maps (planispheres) to locate objects in the sky. By using telescopes we can see deep space objects located millions of light years away from us. The science of astronomy is based on usage of sky maps. Please read "Astronomy Tutorial" on this site for more information.

It would be soooooo awesome if you were able to integrate ascom support for communicating with telescopes or support for NexStar from Celestron. This app, on a tablet with long battery life, able to drive a CGEM mount would be perfect!

@Frodo, you're correct we haven't got the chance to implement settings serialization. But this is on our list for one of the next releases.
1/13/2013 9:03:06 PM

The Windows 8 version doesn't save the customisation once we exit the program. Very annoying to have to do it every time we use SkyMap. Otherwize, very good program for the price!

@PuzzledLass - you have a valid question. But this is a sky map and it shows the sky as seen from Earth; so the map doesn't show Earth because while we're standing on it, we can't see it in the sky.
@Yusof - yes, the majority of star names are of Arab origin. According to wikipedia, "In Western astronomy, most of the accepted star names are Arabic, a few are Greek and some are of unknown origin. Typically only bright stars have names". The orgin of many of our star names is from "Book of Fixed Stars" written around 964 by the astronomer Abd al-Rahman al-Sufi (known as Azophi in Europe).
12/18/2012 9:07:42 PM

Hi...When i visit your sky map i can type in the names of the planets as follows Mercury, Venus, Mars, Jupiter, Saturn, Neptune and Pluto....very strangely (to me at least) if i type in Earth it says search for Earth not found! I would assume as you can view other planets in our solar system that we should also be able to view Earth. Is there a reason why your sky map is saying its not there?
12/17/2012 12:49:26 PM
I always got fascinated watching stars when I am at sea fishing at night. Your Star Map helps me to recognize Orion , Jupiter, Sirius, Al dabaran and few others. And i was suprised to note that many of the names are of Arabic origins. I hope to understand the movement of the stars in every month of the year. Thanks

The installation of our application is not under our direct control.
All applications approved on Microsoft markeplace are going through a testing process (during which the installation of the app is validated). I guess the installation of the app fails due to an issue on your phone.

I would suggest to try this:
- if you have a trial version of our app, please uninstall it
- restart your phone (power phone by pressing the off button for a couple of seconds)
- make sure you try to install it while using a different internet connection (wifi or regular data plan is you have one)

Hello!! Hey, your Skymap app will not install. I'm getting the attention required message over and over.. Can you guys please look into this problem as soon as you get a chance?? Thanks

BTW.. Your other apps installed just fine, and great work! :D
12/3/2012 10:52:19 PM

John H. Cato, jr, R.A.
It would be nice to have a 'slider' adjustment for apparent magnitude just like the zoom function. That way, one could drop off some of the weaker stars and more clearly see objects of their interest. Discreet steps (if fine enough) would work, but a continuous slider would be even nicer. Nice site, BTW.

Thanks Admin. Look forward to being able to save the map parameters but, in the meantime a little bit extra exercise for my wrist will do no harm!
10/18/2012 4:04:09 AM

Please ignore the links sent by spammers. I'm actively deleting the spammers comments here.

I have the option of either:
- use captachas
- denied any posting of a link
- deny comments from people spamming this comments section
- other methods (approvals, etc)

Stephen, I understand you want to save the map parameters somehow for further use. I think that's a great suggestion and I'll implement it in the future.
10/17/2012 9:44:04 AM

Stephen Felce
I use the compass exactly as you say. Actually, it is a little awkward and difficult to adjust accurately, but never mind.

But that is not the point. Having got the view once that I want, I do not want to keep having to readjust to it every time!

Saving and using the link as you say freezes the view and disables all the features. Not really useful as you cannot even click on a star for more info, let alone get at the options.

Not sure who horny is talking to, but the link in his message is unobtainable on my PC and heaven knows what he is trying to say, if anything.
10/17/2012 4:07:38 AM

Hello Stephen. I'll try to answer your questions.

I seldom have people providing feedback longer than 100 characters. So, thank you - splitting your message in 2 sections is the right decision.
Have you tried to rotate the map using the compass rose on the left of the map? There is a knob there (N for North) - if you drag it, then the map will rotate - so that way you can have E on the bottom of the map (useful if you're facing east).
You can save a map for future reference. Just click on Share and copy/save that link.
Flip functionality is there for people using this map with telescopes - the image, as seen thgough telescopes, is often reversed due to the mirrors in the telescopes.

I've noted your suggestions about SE, NE, 45° grid, etc. I hope I can get some spare time soon to push an update for this website.
10/16/2012 5:16:17 PM

Stephen Felce
Hi Admin, Thanks for getting back. I do hope you can address all my points.

I am using the online version, so far with my naked eyes and can see about 45° to either side ie. NE and SE when facing E through my window. I imagine a 90° span would be about as much as one could take in unaided. I have a good pair of 8 x 40 binoculars and a solid tripod but so far have not used them.

[Having seen Saturn, its moons and the rings side on from the Lowell Observatory in Flagstaff, Arizona and even then just as blurred spots and a smudge for the latter cannot see the point in buying a telescope which would be much inferior and less sharp!]
10/16/2012 3:27:49 PM

Hello Stephen, are you talking about the SkyMap for Windows Phone or SkyMapOnline - the online app?
Do you use the app with when looking at the sky through a telescope or binoculars?
10/16/2012 8:35:40 AM

Stephen Felce
Part 2 of 2

3)The grid you get with Azgrid is useless because it split at the wrong points, that is at 30° and 60°, neither of which correspond with the compass. Instead, I would have expected the grid to show at 45° either side, NE and SE from E etc. [But in any case, when viewing at a larger scale the letters NE and SE as well as E would be much better than the grid because not enough of the grid would show to be any real help.]

4) If I click and drag the night sky, sometimes it will not stop unless I do a reset or something else that makes me lose my position and the scale entirely. That is particularly annoying when it happens, which is quite often.

And a suggestion – having set my image scale etc, I would like to be able to save all of that so next time I start up, there it is just as before!

10/15/2012 12:00:59 PM

Stephen Felce
Part 1 of 2 parts because you limit me too 100 characters!

Hi - Your application to view the night sky is very clear, much better on screen than I have seen elsewhere and I look forward to instructions and, hopefully, improvements as regards the following:

I do find these things rather annoying:

1) Taking my situation as the example, the window in my home I view the sky for real faces east, so I would expect to be able to identify where on "SKY MAP" SW and SE are located. You show an "E" but why not also "SW" and "SE"? That, viewing "SKY MAP" a corresponding scale, one would be able to figure out where they are much more easily. At that scale, it is impossible to tell where "SW" and "SE" would be.

2) If I use “Flip Vertical” I still get “E” at the bottom but the image has changed. The actual sky has not, so what on earth is this for, no pun intended?

I seldom comment on apps that I buy but occassionally an app is such value for money that I feel it is only right to congratulate the designers. It is just approaching midnight here and I have spent the last 30 minutes using version 2.3 onmy Lumina 800 to view the night sky. I have probably learnt more in the last 30 mins than I have in the last 30 years. The link to wikipeadia is excellent as I was able to use Wifi to get information on each object that I identified. Well done on an excellent app.

The paid SkyMap app for windows phone has no ads.
There are 2 apps on marketplace: SkyMap and SkyMap Free, but only SkyMap has a paid version. If you buy SkyMap (full version) from SkyMap Free, please make sure that you exit SkyMap Free and start SkyMap (full version).

For people on western USA and Japan - enjoy the solar eclipse today!

Do the adverts disappear on the full paid version? It's not clear from any of the product descriptions whether they stay or go. thanks.

There's a help inside the windows phone application.
We'll consider the idea to publish the same help on a website. Thanks for the suggestion.

the phone camera lens are quite small and limited during night time. They pick way too less light and we can't really see stars using the phone camera. We may consider adding a camera overlay but we're still debating about the priority of this feature.
Meanwhile, we spend some time and energy in the translation of the app in different languages.

I'm not sure what you mean - big dipper (asterism in Ursa Major) will look upside down if it shows on the map above the zenith. You may need to rotate the map to get it right.

Our planet is not displayed on the SkyMap. SkyMap shows the sky as we see it from Earth.

Love the app but frustratingly can't read some of the Skymap pages on my nokia lumia phone. Is there a webpage with explanations of the phone icons and any other pages that can be printed out on my PC for easier reading.?
I would love to learn how to use it properly and have paid for the full version.
4/19/2012 4:10:08 AM

Great App on WP7. Is it possible to realize ist via virtual reality, too??? You can point to sky and see the real sky through the camera lens with a skymap overlay???
4/16/2012 2:13:41 PM

This is probably a very un-educated query but when I look at the sky map of the night sky above Seattle it shows the big dipper upright when in fact it is upside down. I like the map, it is easy to use but this is perplexing to me.

Hi there! I love your app, and look forward to getting a lot of good use out of it. I'm having trouble purchasing the full version however. I have an account set up correctly on the Microsoft Zune website, and all the credit card information is correct and double-checked. When I try to upgrade to the full version through the app though, I'm told there is no credit card on file, but it I try to reenter it, again through the app, I'm told it already exists on my account. Who is making this so difficult? Is it you guys or Microsoft, and why?

@Kari - I'm not sure who was producing that SkyMap v3.0 application you were using in the past. What was the platform you were using it on (PC with Windows, Windows Mobile 6 or something else)?
Star density and removal of deep sky objects... Yes, I'll consider to add them as options on the website. Thanks for the suggestion. Keeping track of the time automatically on the website app is a little bit more difficult (and that's why there is a Time Now button which can be used for that purpose)
Our windows phone 7.5 app already has these features.

In order to work around this issue users have to click Done, in that dialog, and restart the calibration by using the calibration button in the sensors bar (or disabling and re-enabling the point to sky feature).

- ability to add and to reduce the brightness of the sky, and in such a way to make visible only brightest stars seen with the naked eye
- opportunity to put the time flow into automatically e.g. day at a time in a few seconds and keep track of changes to skymap
- ability to remove deep sky objects

You're welcome, Arif. I've added Lahore with the coordinates provided by you. To be fair, those coordinated do not match the center of Lahore, but they are a bit SSW from the center (and they match to Kot Araian).

Looking forward to consideration.

Thanks, Kirk. And I'm glad it works well for you (and other people in Australia :)). I was already scratching my head why it should behave differently there.
10/7/2011 9:26:42 AM

You wouldn't read about it. After recalibrating and trying again, the cardinals are correct in portrait mode above and below horizon. In landscape mode they now appear correct above the horizon (most usefully) but inverted below the horizon.

The phone, BTW, is an HTC Mozart. I can still send you an e-mail if you with.
Thanks Ciprian.
10/7/2011 1:31:06 AM

Kirk, can you try landscape mode, pointing down (under horizon line)? Does that points in the right cardinal direction for you?
I really appreciate your help.
10/7/2011 12:44:59 AM

Excellent. I look forward to it; been waiting for Microsoft to release this functionality for ages :-)

Re the portrait orientation pointing up, above the horizon - yes, this is how I initially tested.

BTW, sorry about the multiple post. Refreshed the browser page mistakenly
10/7/2011 12:40:37 AM

Kirk, thank you for letting us know about the issue in Australia. Yes, unfortunatelly we didn't test the app in southern hemisphere - but we'll fix this issue as soon as possible (we'll try to release the next update to marketplace in a few days).
Do you see this issue when you're using the phone in portrait orientation pointing up, above the horizon line?
10/7/2011 12:37:32 AM

Just updated to the version with compass support and calibrated fine. However, the cardinal directions are inverted from the direction I'm actually pointing - compass is telling me I'm pointing South and the map as such when I'm actually facing north (holding phone in the normal orientation). I have played with the 'map orientation' to no avail. Assuming it must be a northern vs southern hemisphere issue since I'm assuming you're in the northern - I'm in Australia. Still, it might just be a user issue :-) Any suggestions?
10/7/2011 12:00:49 AM

SkyMap v1.5 for windows phone v7.5 (mango), with compass support, is available for download on marketplace.
From our experience, the compass calibration may take quite a while especially when done the first time. Take your time, shake the phone well, have patience and it will eventually get calibrated. Also, if you can't get it calibrated first time, a phone shutdown/restart may help.

SkyMap v1.5 for windows phone v7.5 (mango) was released to marketplace yesterday (Oct 1st) and is pending Microsoft's certification. This version has the compass integration (full point to sky feature).
10/2/2011 9:41:45 AM

@Baz - the site has London in the list of cities in the Location combo box; I assume the confusion here is created by the Search text box which is used for sky objects. So I'll add a label to that search box to make it clear.
@AnthonyS - yes, the SDK was available but the driver for compass API became available only this week (after the official Mango release). So we're working to release 2 Mango editions very soon: v1.5, targeted to be released for certification this weekend, will include a full point to sky feature (assuming you have a windows phone with Mango and compass drivers) and v2.0 - soon after - with a new map rendering approach (including Milky Way and contellation artworks)
@Maurie - great suggestion, I'm going to add telrad circles on the "printable map" view
@all - thank you for all your feedback. It's greatly appreciated!
9/30/2011 9:22:14 PM

Awesome site! Very well put together. I've shared your link on Hope you don't mind. ;)

Could you make the telrad circles print on the "printable map" view? That would be a handy feature.
9/29/2011 4:56:08 PM

The Windows Phone 7 app works well, but I was wondering when the Mango edition was going to be released. The SDK has been available for a while now, and I'm really looking forward to being able to use Point-to-Sky with a working compass.

Finally! A useable Internet Star Map!!! Nice work and Thank You.

If you don't know where London is - how can you find the stars!!!
9/25/2011 1:27:13 PM

the moon phase can be determined by clicking on the moon - it provides moon phase information (e.g. 0% is new moon while 100% is full moon)
I'm not sure if the request implies a graphical display of the moon phase (which is also possible but it requires some work)
8/29/2011 2:08:37 PM

It very practical and easy map to use for any location.
It will be better if we can see the moon phases.

Pluto was added to this website.
SkyMap wp7 applications will get Pluto in the next update (probably during the next 1-2 weeks).
7/14/2011 7:21:35 PM

Just a quick note about our SkyMap for windows phone applications.
People can buy the full version of SkyMap from inside SkyMap Free (for $1.29). Please note there are 2 apps: SkyMap and SkyMap Free. If you buy SkyMap from inside SkyMap Free, you have to exit SkyMap Free and start using the other app (SkyMap) in order to see no ads and get all unlocked features.
7/12/2011 11:16:33 AM

Great news! Thank you very much this will make it the best skymap app out there and I'll definitely be buying it.
7/3/2011 2:24:15 AM

Well, Pluto is not considered a planet anymore (but a dwarf planet instead). And frankly, a medium size telescope can't really help us to find Pluto (due to Pluto being so dim).
Anyway, I understand there are people interested in the position of Pluto, and I've decided that I'm going to add Pluto to both my website and phone apps.

Daily/monthly maps of the sky can be obtained on this site by changing the map time (see the map menu).
7/3/2011 12:13:11 AM

Where is pluto on the list of objects to find in the sky? I'm a plutophile and this is really disappointing.
6/28/2011 12:23:19 PM

i"like to have mounthly and daily map of the sky to be able to know what i see in the night sky if you please inform...
6/23/2011 7:46:09 AM

J, you're right - higher (magnitude) numbers corespond to dimmer objects. For example, Vega is magnitude 0, Deneb aprox 1 while Polaris is 2. In a city with medium light polution, we can see stars up to magnitude 4, while in a rural area with very low light polution, we can see stars up to magnitude 6. By using small/medium telescopes or binoculars we can see more stars - let's say up to magnitude 8 - 12 (depending on what we use).

Also, for windows phone users - please try our SkyMap application (for free). We've submitted to marketplace a new update (v1.2) and included new features like map rotation, a beta point to sky and astronomy picture of the day. Enjoy!
5/24/2011 12:38:29 AM

Found this quick useful info for beginners: On the astronomers' scale, larger numbers mean dimmer objects. Negative numbers are reserved for the brightest objects. i.e Jupiter is around -1.89 whereas say Castor is around 1.89

Sorry if this has been mentioned somewhere else in the website.
5/23/2011 7:38:33 PM

Kevin, assuming I understand your question, yes, you can include the sky charts generated by this website anywhere you want as long as you mention the source. Thanks.

Today it's the aniversary of 50 years since Yuri Gagarin became the first human getting into the outer space.
50 years is a lot of time (half of century) and we still barely have only few people in the lower Earth orbit. We can't even send people back to the Moon despite the fact that our technology seems way more advanced.
Let's just hope that the commercial interest will spark improvements in space exploration.
4/12/2011 10:53:08 AM

Pierre, thanks for your comments.
And yes, I was thinking about spending some time with ASCOM drivers. Your suggestion is great - I'll definetly like to implement it but it may take a while to make it work and release it. Porting ASCOM drivers on windows phone platform seems pretty challenging.
4/8/2011 10:10:24 PM

Pierre Stromberg
I recently purchased SkyMap for WP7 and I was very impressed. Very snappy performance. For future releases, do you have any plans to provide any ASCOM support so that it can remotely drive EQ6 type mounts through EQDIR? Thanks again.

4/7/2011 8:03:58 PM

THANX...:))))))))))))))))) GOD BLESS:))
3/19/2011 9:18:54 AM

ivie, yes, we can talk about your request - please send me a private email (ciprianboboc @ gmail . com)

I like your skymap online. is it anyways I could embed it in mt astronomy blog ? thank you.

We've just published this FREE game for Windows Phone 7: Memory Bubbles
If you have a Windows Phone 7 and want to train your memory or just enjoy popping bubbles, please give it a try.
3/17/2011 12:36:41 AM

Dave, congratulations on your phone.
I've sent a private email to you. Our SkyMap for Windows Phone 7 describes a few of the functionalities of our application.
Here are a few basic steps to use with our app:
- drag the map (click on the map and drag the finger on the screen)
- zoom the map (use + or - buttons on the bottom of the map or use pich gesture - drag 2 fingers at the same time in opposite direction on the map)
- rotate the map by using the compass bar (click ... on app bar and rotate left or rotate right to change perspective)
- change map settings (by default the map will show how the sky looks at the location provided by the phone's GPS at current time) - these are customizable settings (go to app bar, click on ... and then pick settings)
- click on any star to get information
- use search function
- etc

And do not hesitate to send us more feedback.
We're currently working on the new release of this application - more features will be delivered pretty soon!
3/16/2011 8:16:53 PM

Recently purchased a LG Quatum (C900) from AT&T Yesterday I (think I Hope I did) loaded you "Sky Map" on my phone Now all I need is a set of instructions to use it ( I am not to savy in computerize I am a senior cetinse) Need all the help I can get I belive yor app is very worthwhile having I am a amuetur astronogler
3/16/2011 4:32:46 PM

Steven, thanks for your comment. "Flip the map" functionality will be in our first application update, which we plan to release this month.
There were other people asking for the same functionality and I've already implemented on the website.
"Flip the map" is also useful when people are looking through telescopes (the sky image seen in a telescope is often fliped due to lens and mirrors used by telescopes).
Adding sattelites and location of space station is a good suggestion and we'll keep on this our list for future releases.
3/4/2011 12:32:52 PM

Steven R.
I like this app! I would like the addition of the location of the space station and the ability to "reverse" the screen. In other words, I need to hold the phone up to the sky to get its screen to match the sky, if it could be "mirrored" then I can match the stars with it held down, do I make my point clear?

2/28/2011 7:35:35 AM

Sirius, it's not our goal to make Windows Phone 7 sky map application "work like" any other sky map application produced by a different company. While there are some similar expectations for any (sky) mapping application, there will always be differences between various applications and there will be limitations imposed by the platform where the application is running. For example, Windows Phones have compass hardware but there is no API to allow the applications to actually use the compass (and for that reason, no sky map application on Windows Phone can implement a "point to sky feature" until a future Windows Phone 7 OS update will expose this API).
Our Windows Phone 7 SkyMap application has a free trial in place - so anyone can use the application for free as long as he wants. But the full version has no ads and doesn't have any more "locked" features.
2/27/2011 4:37:03 PM

does skymap work like the google sky map android?
2/24/2011 9:29:47 PM

Abenaton, thanks to you and all others who downloaded and bought the WP7 version. I've included this request on our feature list for the next application update. I'll implement this feature on the website, too. Thanks for the suggestion.
[update - feature implemented on the website: Options - Flip]
1/30/2011 11:07:51 AM

I just bought the WP7 version. Great! Thank you.
Like Mike and Renee, I was surprised to find that the sun was risind West this morning until I realized the sky map was reversed. As others, I feel rather uncomfortable with this view although I understand why it is as it is !
However, I will, like many, wait for the "flip" function with impatience.
Again, thanks a lot for helping the amateur admire the wonders of the sky.
1/29/2011 12:22:48 AM

Flora, thanks for the suggestion.
You can turn on now the Alt/Az grid but there is option available to show the celestial equator. But we'll try to add the celestial equator to the map as soon as possible.
1/25/2011 1:25:07 PM

just a question: how can i see the celestial equator on this map or it's poles or zodiac....???? I"m confused !!!! :D
1/25/2011 12:11:51 PM

OMG I really LOVE this site :xX >:D< Tnx
1/25/2011 12:02:11 PM

Jay, I understand your concern about the owner identity data. I would like to suggest to you to take a look at Microsoft's Windows Phone 7 Privacy Statement (Display of Advertising section) -
Also, if you like this SkyMap app, you may consider getting the full version (priced now at $1.29) - because the full version does not use the ad control at all (and it doesn't have any restrictions).
1/23/2011 7:49:04 PM

Sorry for the double post. I reloaded the page in my phone's browser and it re-sent the comment.

Thanks for the quick response. I actually read on a developer's forum where someone asked why his app requested ownership. Same as yours, it turned out to be the ads. That's still not cool in my opinion though, I try to keep my personal information from advertisers with browser extensions. Hopefully these advertiser permissions change soon.
1/23/2011 9:42:42 AM

jay, thank you for your very good question.
We do not collect owner identity data. Our app was flagged on marketplace as using "owner identity data" because the free trial uses WP7 add control. But Microsoft adCenter team claims that the Ad Control doesn’t use Owner Identity, and instead uses only anonymized profile targeting parameters – such as age/gender. Also, only the free trial version of our app is using indirectly data connection and web browser due to the same ad control.
1/23/2011 9:21:27 AM

In the Windows Phone 7 app, why do you collect owner identity data?
1/23/2011 1:27:46 AM

George, that's actually what we are working on right now - a Sky Map application on windows phone 7. I hope we'll release it by end on this month (January).
1/8/2011 7:46:11 PM

Great product - online map.
It will be fine if you can offer offline version to be downloaded on portable books when we are in countryside, without any internet or wareless cover.
1/7/2011 7:10:52 AM

Just found the site and Really enjoy it,wish I'd have found it sooner could have saved the cash I spent on a sky map book Great Job and keep up the good work,Thanks
12/23/2010 12:50:31 PM

Johnny, did you try the "Printable Map" menu entry? That will create a "printer friendly" page (white background with black dots). After that map is generated, you can select (from the browser's menu) File - Print (using Landscape mode).
What browser do you use? Have you maybe hit a webserver issue? Or the print option is not what you expect? What do you mean by "nothing there"?
12/9/2010 6:25:03 PM

I really loved your site until I tried to print. Nothing there.
12/9/2010 5:27:59 AM

Barbara, Venus is now in constellation Virgo (it rises at aprox 1:30am - so it can be seen probably after 2am)
You can set the location to your city (click on the menu location and input the name of your city in the location text box + hit enter). After that, you can type Venus in the search button and click Search.
12/2/2010 7:45:15 PM

I want to know where Venus is located in the sky presently over

Great site - added to my favourites - I'm new to the astronomy hobby with my first telescope arriving for Christmas!
Love the constellation list and the sky map is great
Big Thank You for this site!
11/24/2010 3:14:20 AM

Please try the new HTML5 Sky Map - it's under development and new features will be added soon (e.g. Tycho and nebulae catalogs, map transitions, probably some map animations, etc). Let me know what you think!
10/31/2010 8:59:48 PM

J, that sounds like a good deal. Enjoy your new binoculars!
You can buy an adapter from ebay or other Internet stores. I've got mine from ebay ($1 + $4 shipping from China) a few months ago.
10/30/2010 9:58:08 PM

I think I found a nice pair of binoculars for an amazing price to get started. Celestron SkyMaster Giant 15x70 Binoculars with Tripod Adapter for $65.80. I already have a sturdy Targus tripod so I just need the adapter.
10/30/2010 8:21:27 AM

Thank you for the quick response! The tutorial was also very helpful. Im somewhat familiar with the technical terms used since I have a SLR camera. So when I see a 600X magnification telescope its like the 12x digital zoom on the PS cameras. Ill keep reading and learning and once again thank you for the suggestions.
10/29/2010 10:04:22 AM

J, depends on your expectations. Please check the Astronomy Tutorial - Telescopes page on this website.
There are multiple options:
- dosbsonians (they are bigger, heavier, but you have to starhop - find the targets and manually move the telescope to compensate for the Earth rotation)
- goto telescopes (probably a small refractor in your budget) - after a short alignment process, the telescope will find the targets by itself; they're also easier to carry
You may also start by using binoculars. 9x50 or 8x40 binoculars are good for astronomy (you'll also want some decent quality binoculars to achieve good focus and gather enough light - coated lens are recommended)
10/28/2010 11:33:50 AM

Great site! Im currently interested in starting this hobby at home since I discovered a nice flat concrete terrace on my roof, perfect for setting up a telescope and big enough for a chair a small table and laptop. I was wondering if anyone could recommend a telescope, brand or specifications to get started? My budget is between is $200-$300.

I am very interesed in star charts and I find your web sight the greatest for me. I am a beginner in star searching!
10/14/2010 6:18:07 PM

Rick, thanks for reporting this issue.
M31 is not shown due to its proximity to M110. Skymaponline has a label overlap detection algorithm. If there are 2 potential overlaps between 2 labels (M31 and M110 in this case), only one will be displayed. I agree with you that the bigger (brightest) objects should be displayed in this case. But until I came up with a fix, there are a couple of work arounds:
- go to higher zoom levels (and both M31 and M110 will be displayed) or...
- use Search (Search for M31) will keep M31 visible (no matter what other label conflicts are around)
10/9/2010 4:12:01 PM

Rick Allen
I am viewing from Hong Kong. Of special interst to me is M31. When I zoom past a certain point, M31 in the Andromeda constellation disappears and is replaced by M110. Why is this?
10/9/2010 1:28:26 AM

@ Mike & Renee
There is a compass control on the left of the map (under the zoom control). We can click on it and change the map viewpoint. By default, it's facing south (south is down). But the map can be rotated in any direction.
For example, if you click on the bottom of that compass control, north will go down and west will be to the left. Like any planisphere, sky maps orientations are different compared to standard earth maps (the perspective is different - looking up opposed to down). If we face south and look up, then east is on our left :)
However, it makes a lot of sense to get a "flip map" feature - especially for the users using telescopes. The image in the telescope is flipped - so I've added this request on my "to do" list.
Thank you.
10/2/2010 2:45:22 PM

great site!! went straight to my bookmarks!!THANK YOU for your great great work
10/2/2010 12:40:06 PM

Mike & Renee

Could you design your sky map with the points of the compass? W / N / E/ ??
West should be to the left of chart or is there a way to flip chart to match the night skys?
This would make viewing much easier for users:)We really enjoyed your site.

great site!
9/30/2010 10:35:31 PM

John, you can use Options – Map Size and get a higher resolution (up to 1300x800).
In the future I may implement a feature to fill the whole browser window.
