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
