Comments about Mobile Observatory 3 Pro - Ast Android Version

Cool app. This app has almost everything. Maybe one recommendation: please add Field of view to the objects, depending on sensor and focal length (something similar to Telescopius). It will help very much for observing and astrophotography and it doesn't need to show real pictures. It can be a small circle showing only the size depending on these parameters. Thanks and keep it up. Really nice work!
This app has a lot of features. I'm just a rank amateur but really love to look up at the night sky. The app helps me identify an object. On occasion certain events draw my interest and It helps with when and where an event will take place in the night sky. I've had it for years now and still have the same app. Works great and keeps updating it's database of objects.
Very good, complete and capable astronomy app. My only two minor niggles are the on-screen controls are at times a bit small for a phone screen and there's no way to turn off diurnal motion, which means the chart drifts when zoomed in. But that's about it. However there's been no update (as far as I can tell) in 14 months. Is the developer still active?
