Comments on Telescope calculator pro for Android

★★★★★ _ HajoVonta · Jan 28, 2020

Very good app that calculates necessary information when using telescopes, eyepieces and oculars, and also shows the picture what you can expect. Large database of telescopes. Nice work! Very useful.

★★★★★ J adkins · Jan 15, 2020

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.

★★★★★ kevin ware · Oct 3, 2018

Great start. I'd love the addition of Lunt/APM eyepieces. Also, I wish the Messier objects were true colors and not Hubble imaged crops. Keep it up.

★★☆☆☆ David Poole · Feb 10, 2025

Does it update for current telescopes, lenses or cameras

★★☆☆☆ Robert Merchant · Feb 15, 2021

Needs disclaimer, not for someone thinking about buying a telescope or any beginner
