Telescope Calc

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

Recent changes:
v1.2.0
- added ability to specify barlow lens multiplier
- fixed validation of input data
- minor bugfixes

v1.1.1
- fixed broken unlocking of eyepiece parameter panel that happened for some aperture/focal length combinations

v1.1.0
- fixed handling of aperture when using inches
- added calculation for field transit time and power per inch of aperture
- added more settings and made existing one easier to use
- bugfixes
