This is great. I am an amateur astrophotographer, just as a hobby. When I'm planning for shooting a specific celestial body I can easily fast forward to night and see when and how long is the most suitable way to plan a shot (shooting deep space objects take total of many hours of exposures, "locked" to the same point in space using a tracker). Also know when moon and sun will rise/set which is crucial as even a tiny amount of sunlight or moonlight ruins the already-super-faint data. Also has the mobile app, which is equally useful. Definitely recommended if you're getting into astrophotography, or just to see how time and Earth's rotation affects what is seen in the sky.
