My Astrophotography
Database

Content:

With this database of my astrophotos I can get an idea how many nights per month/year the sky conditions is good enough at my places for astrophotographing, see the statistics. Each object has one file that contains all of its images from different dates.

Daves limit is the theoretical resolution of the telescope/lens. It depends on the diameter of the lens and the wave length. In this case it's calculated for the green wave length. " stands for arc seconds, one degree is 3600". The Moon is 1800" wide, Andromeda galaxy 10'000" wide. The stability of the atmosphere limits the resolution, often called seeing, very good seeing is 2".
