Ratings and reviews

Saves a lot of time figuring what eyepiece to use and so on .Perfect for astrophotography and video and just right for new students learning how to operate any scope on the market like me.This app is worth 10 Stars .The best on the market and a reasonable price.

Good day, I was wondering if it is possible to add a digital zoom and ISO feature for the camera section? If not, it is OK. This is the best well thought out app I have come across. This app will greatly assist you in determining what upgrades you should make to your gear. Thank you again for creating this app. JR

I do find the app very useful for astrophotography. I would like you to add a .5 focal reducer selection under the Barlow lens section. It would be handy to have a save function to save my different telescope and camera combinations. Thanks for the app.
