By Joshua Bury

Open iTunes to buy and download apps.


Observer Pro is a groundbreaking app for advanced astronomy planning. No more guessing when that galaxy emerges from behind that pesky tree. No more estimating how many hours you'll be able to image an object. Observer Pro gives every astronomer the info they need right at their fingertips!

What astronomers are saying:

- Tom Mote, Professor Emeritus, Astronomy

Exclusive features:

✓ Over 14,000 deep sky objects included, all with closeup reference photos. No need to download anything after install! Advanced sorting and search make it easy to sift through all of them to find which objects belong on your observing list.

✓ Measure your local horizon in minutes with your iPhone 4*!

✓ Unique charts completely take the guesswork out of predicting object visibility. Your house, trees, mountains, or any other obstructions are completely factored in to all visibility charts.

✓ New to astronomy? The Popular List shows trending objects based on observations logged by Observer Pro users. Now you can view a list of the best objects to observe based on actual observations!

✓ Keep a list of your favorite observing sites, each with their own local horizon. Compare object visibility between sites to find the best spot to setup your scope.

✓ There's a lot to observe! Observer Pro gives you a place to maintain a list of your favorite objects as well as an observing list that you can take with you to the eyepiece (red-screen night mode is included). Observer Pro displays easy to see badges next to objects that are favorites or that have been observed.

✓ 7Timer! astronomical weather forecasts for your observing sites are viewable without leaving Observer Pro. They give you the outlook on cloud cover, seeing, transparency, and more!

✓ Simple and intuitive interface makes all these powerful features readily accessible. You don't need to be a Certified Astro Geek to use it!

What are you waiting for? Purchase Observer Pro and you won't know how you did astronomy without it!


* A device with a magnetometer and gyroscope are required to measure your local horizon. If your device does not have these hardware features, you can still set the local horizon in Observer Pro to a constant value or import a local horizon data file after measuring it with a friend's device, your telescope mount, or just a simple compass and protractor!

Customer Reviews

Fantastic App!

Totally worth the $10 - one of the best astronomy apps out there!
If you are an observational astronomer, you will use this app every time you observe. Gives you an amazing amount of information about an object's visibility at a glance. The object images themselves are worth the cost, but there is so much more! The ability to enter multiple observing sites and enter and save multiple horizons is fantastic. I'm totally psyched that version 2.0 (as a native iPad app) will be forthcoming soon! This app and SkySafari are all you need for planning an observing run when using an iPad or iPhone (I use both platforms). Thanks for a fantastic app!

ObserverPro - - WOW!

I saw a review of ObserverPro in the "Astronomy Technology Today" magazine that came in yesterday's mail. I was so impressed that I immediately purchased and downloaded the app to my iPad2 3g. If you have read the other available reviews you already may have ObserverPro up and running on your iPhone or iPad. In other words, I am probably "preaching to the choir" when I say that ObserverPro is the most impressive astronomy app that I have tried out. I enthusiastically commend it to you!

Tom Mote, Professor Emeritus, Astronomy, St. Mary's University

Great program!!!!

If you have a goto scope and an iphone, this program is all you need to find the best objects to look at on any given night, now or in the distant future. It is simple and easy to use also. The price is good too. Don't even bother paying big money for a planetarium program like skyview or starmap if you have a goto scope (i bought both and this program makes them obselete). Just get this and you'll have all you need except for the info on the planets.
