Cocoon Nebula, a LRHaGB picture

nvc55

one more with the portable equipment shown here:

The Cocoon Nebula. Total exposure time ~11 hours. Please see the attachment.

The main part of the exposures was done using the ZWO asi1600MM cool camera and the NP127is F5.2 refractor. The Portable Mount used was the TTS-160 Panther.

The main part of frames/subs were taken in my backyard, 22-23 aug-2017, less than 10 km from the citycenter of Copenhagen, Denmark.

Thanks for stopping by.

One more processing attempt, Photoshop usage, where I took all LRGB subs and used them as a LUM layer.

The result is attached. BR. Niels

The "LRGB frames=artificial Lum master frame" is here. As it can be seen I will have to make a flatbox to get rid of the vignetting, but for now I have used gradientXterminator instead.

Please see the jpg file attached.
