Moon exposure calculator

I have previously wrote and article about how to take successful moon pictures and today I have worked on a moon exposure calculator.
The moon exposure calculator is a tool for photographers feeling like taking pictures of the moon, it will give you the estimated shutter speed required based on your ISO, aperture, moon location, weather condition and moon phase.

This script is a modification of Shaytech Moon Exposure Calculator to which I have added more variables like moon location and weather condition.
