Hello everyone,

I've made a little app for Android phones and tablets that you might find useful.

It's called Telescope Calc and it's an easy to use calculator that will output the following parameters for given telescope-eyepiece combination:
  • resolving power of the telescope
  • star magnitude limit
  • diameter of exit pupil
  • magnification
  • field of view
  • surface brightness

You can also save your configurations for later. Additionally, there are 4 predefined formulas for finding minimum, maximum, optimum and wide-field magnifications. You can set the size of your eye pupil in settings, and it will be taken into account when calculating some of those.

It's also optimized for tablets, meaning it makes use of extra space to make itself even more comfortable to use.

It's available now for free from Google Play and SlideME (for those without access to Google Play)

I'd be happy to hear your feedback.

Nice.. thanks..any possibilities of an ad-free paid version coming down the pipe?

Also the link to the G-play store seems to be broken.

Thanks for writing this app, and for posting it here. It seems to work well on both my Nexus 7 tablet, and my Samsung Galaxy SII.

Thanks for the feedback. Fixed the link to Play Store. As for paid, ad-free version, I'm not planning that anytime soon.
