Makes navigating the night sky so easy!

I'm a theoretical astrophysicist, but I've never been good at finding faint objects in the night sky. This app (on my 12" Dob) changes everything! I really love it, and recommend it to everyone. Needs no alignment; if something is hidden behind a tree, I can just pick up and move (which is a workout with a 12", but I need my exercise), and I'm instantly observing again with no alignment. I've found things and understood structures I never had before. The system is great, and the app specifically works really well. Looking forward to more features!

Useless app

My parents got me a Explorer telescope for my 13th birthday and I used the app for the first time. And the app is useless, whenever I start alining the stars and planets and stuff, they are in the wrong spot. Please developer respond 🙏
