Description

First shot from new location. After the move I know have the eastern sky in front of me. This is away from cologne so much darker skies yayyy. However I am still not happy with my guiding. Even after the PEC training in EQMod I am now at a total RMS around 2... Still room for improvement.

B

Remastered in Pshop to get the colors out better

C

Added 8 more 20 Min subs from tonight

D

Stretched a bit more to get the blue out better

E

Well, looking back at it on my Macbook whilst it was dark, the last version was stretched and post processed to much. So back from the start with less intensive stretching, less noise reduction and more selective contrast enhancement. A lot finer details are now visible.

F

Minor curves adjustment and a bit more saturation in the mid tones
