Hi Martin! I'm impressed by your result. Would you mind posting some details (your jpeg file seems not to carry any metadata)? I tried to follow your advice and come close, but cannot solve two problems:
1. Even with the CA module on, the stars show strong CAs, especially in the corners but in the center as well. That makes the picture a bit colorful even in lower resolutions comparable to the picture you posted. How did you get rid of them? 2. I can't get rid of a medium frequency noise phenomenon that I observe regularly in my own pictures as well. It's a "cloud-like" purple/green shift of the background. Do you have any suggestions?
