This review only applies to my use the FREE version! As an amateur astronomer and from what I have seen and used, this app is very useful. My only downside is, there is no way to add the following... barlow / powermate (various from 1.6x to 5.0x) - focal reducer / field flattener (various from 0.6x to f3.3) - coma corrector If these were added to the equipment database, then I would award it five stars (pun unintended).

All the functionality I was looking for with nice extras I wasnt thinking of like dark mode with red lighting. My only wish is for object types to be displayed at the bottom next to their designation when clicking between objects. I'm still learning the sky

Once you get used to navigating around, it's really cool. The first app I check to decide if and when I get my 8" dob telescope out. Helps me plan my viewing times.
