Description

This is the Cocoon Nebula and surroundings, an interesting mix of an emission nebula (SH2-125), a small reflection nebula vdB 147, and dark nebulea, including LDN 1042 and LDN 1045. This is a (L-Ha)RGB composition. Quite a challenge to process in order to get a good balance of the bright and dark nebulae and all those stars!

Title: Cocoon nebula LRGB new processing

Description: Not being totally happy with my first version, I reprocessed my data from start. This time I did not use the Ha data. Ha is so strong on the emission nebula that it was hiding the faint reflection and dark nebula signal. I think this version without Ha is more balanced. I also had very strong coma on the stars probably due to bad collimation of my refractor. BlurXterminator v1 was not correcting the problem correctly (many stars were doubled and there was still bad color fringes around stars due to the fact that I did different color filters before and after meridian flip). The new blurXterminator v2 (with AI v4) is so much better at correcting star defects that I could correct almost all star deformations and color fringes very easily!

Hope you like this new version!
