This is my first image here in AstroBin. It has been the first light of my new Red Cat 51. I have been doing astroimages with my old Nikon 80-200 f2.8 and Nikon 200mm f4 but I finally decided to stop fighting against CA and upgraded to my first APO!!
Even when I shot 33 240" light frames for this image, I only got 7 good enough to stack (the wind ruined all the rest) Anyway, I processed these 7 using the following workflow:

RawTherapee: RAW convertion, flat field correction and gradient correction.
DSS: Stacking
rnc-color-stretch: Stretching
GIMP: Levels adjustment
RawTherapee: Final cosmetic (small) changes.

The final result is quite noisy due to the small amount of light frames stacked! I hope to improve next time.

The second version has been made removing the stars using StarNet++ and stretching dust separately. Again unfortunately there is not enough data in the faint details, so they appear too noisy.
