Description

And once more the Rosette Nebula. This time with my new 8" f4 Newton. The moon was so close that i decided to use the 7nm h-alpha filter. However, the moon background is still visible and hides some of the weaker details at the edges of the nebula. Well, next time everything will be perfect :D ...

EDIT1: I decided to convert the picture into b/w and played a bit with the contrast.
EDIT2: Fully processed with Pixinsight!
