Telescope Calc
Free AppAbout Telescope Calc
Quickly and painlessly calculate operational parameters of any telescope and eyepiece combination.
Useful for:
- comparing telescopes and eyepieces
- finding right set of eyepieces for your needs
- checking parameters of specific scope-eyepiece combination
- people new to astronomy - to get the hang of the relations between various parameters
Telescope Calc will calculate:
- resolving power of the telescope
- star magnitude limit
- diameter of exit pupil
- magnification
- field of view
- surface brightness
- field of view transit time
- power per inch of aperture
Features:
- easiest to use telescope calculator out there
- immediate results
- allows to set the size of your eye pupil and takes it into account during related calculations
- 4 predefined formulas for finding minimum, maximum, optimum and wide-field magnifications
- can save your configurations for later
- optimized for tablets and phones

I would add four things: 1. For the transit calculation I would add a slider for the azimuth angle in order to take into account the object's position in the calculation. 2. A section for CCD calculations. 3. A section for positive projection calculation. 4. An option to export the calculations as either a photo or text (clipboard).

I did not give it 5 stars because it needs a night mode as using it as it is will ruin night vision Saving settings also needs a tweak to auto load last saved setting on. Add night mode ( red screen and keys and I will give it 5 stars
