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 (even if you're not a Certified Astro Geek). You won't know how you did astronomy without it!
Observer Pro gives you the information you need in an easy to digest visual format. Use the simple interface to painlessly plan your observing and imaging. Easily search through hundreds of potential objects to figure out exactly how you want to spend your time at the eyepiece.
Find the best time to observe any object. Plan for tonight, next week, or three months from now. Observer Pro can use your local horizon to give you the most accurate picture of object visibility. Compare multiple Observing Sites to determine the best spot to setup your scope.
Reference photos are included for all 14,000 objects in Observer Pro. No downloads necessary! Object catalog includes complete NGC and IC catalogs.
Use your iPhone to measure your local horizon. All visibility charts and calculations factor in your actual horizon. Take all the guesswork out of planning your observing. Get the most out of your imaging time.
Easily view when and where an object's visibility will be best in your sky. The Sky Map shows you where the object is amongst the stars, and also visualizes where the object will be in your sky. View a close-up Finder Chart to help locate faint targets.
