Extraordinarily useful app for preparing to view common objects. I don't know we managed to do this before Observer Pro arrived. Indispensable!

I love the app! Very useful and well presented information. Please update it for iPhone 5's screen size and a retina display. I bought this app thinking that it already was updated for my phone. I am also looking forward to an iPad release.

$10 and no updates? How about some sharpless catalogues or an option to download comets and satellites? I just feel like i would have been better off with the orion app which controls your telescope as well. Please bring us more catalogues!

First got this to use with my 6" reflector--the app's ability to show you what objects would be up, and which would be blocked on your local horizon (trees, etc.) was very useful, and worth the cost of the app alone. My one regret about that feature, especially with the 6", was that the app catalogued only deep-sky objects, and not individual stars--given my limited aperture then, and that I was mostly under suburban light pollution, most of my observing was of binary stars. (The simple workaround was to find an NGC or Messier object near the star I wanted, and voila!) Now that I have a 12" scope, and I can properly see the deep-sky objects this app was built for, I can fully appreciate everything it does--the app's visibility charts clearly show how well a given object can be seen at a given date and time (because of more or less interference from moonlight, object altitude, etc.), and they are both accurate and indispensable. Also, a summarized graphical version of the visibility info is available right in the object list, so it's easy to tell at a glance which objects will be visible, and when--and a sortable list lets you use the information to best advantage. If you're already familiar with an object you'll be observing (Ring Nebula, Whirlpool Galaxy, etc.) --and can find it on your own, then this app will provide about all the info you need to see it at its best. If not, it makes for a perfect combination with SkySafari, each app providing what the other doesn't. To the creator of this app, bravo and thank you!
