Description

Here is my attempt on the Cave Nebula. I just love this target, it really looks dramatic and dark. Full moon and no astronomical darkness here in Germany doesn't really help but hey what can you do when there are clear skies ;) Hope you like it, let me know what you think!

Had a look on my mobile yesterday on that one and it looked far to stretched and noise reduced (patchy background). Reduced all a bit and repaired some ugly looking stars with star spikes.

C

Less messing about with the spikes

D

It was just to dark ...
