calc-o-scope

With CALC-O-SCOPE, your iPhone does a lot of the calculations for you.
You have the option of saving up to 4 different presets and calling them up again with a tap.
Here are some features:
- focal ratio
- magnification
-Light gathering ability
- Exit pupil (with warning)
- resolving power (with warning)
- min. magnification
- beneficial enlargement
- max magnification (with warning)
- moonphase (with calendar entry)
- julian date
- show UTC
If you wish, Calc-o-scope will show you your current position and help you align the telescope with a compass.
Also take a look at my calc-o-scope website (german). There you will find a way to equip your iPhone with a system-wide red filter with a triple click (no more flashed eyes if a message pops up).
Have fun with calc-o-scope
