Below is a list of links to helpful websites, Android Apps and software that I have found useful in my photography.

Clear Dark Sky is a website that shows at a glance when, in the next 48 hours, we might expect clear and dark skies for one specific observing site.  I find this useful when planning a nighttime photo shoot.
