Thank you for that wonderful program. I enjoy it very much!
I see that you've gone through great length to simulate real atmospheric conditions. What I miss though is the ability to dim the stars to the point where they look just like the stars that I see with the naked eye, outside.
Is it possible to add a slider to do this? So I can manually adjust what stars are visible at my real viewing location? Or are there atmospheric conditions to reckon with, and is it not as easy as I suggest?
