Veil nebula (NGC 6960)

The Veil Nebula (NGC 6960) is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop, a large but relatively faint supernova remnant. The source supernova exploded between 5000 and 8000 years ago, and the remnants have since expanded to cover an area roughly about 6 times the diameter of the full moon. The distance to the nebula is about 1,470 light-years from earth.(dixit Wikipedia)

To take this photo i used the following setup:
Scope: TSOptics 80/350
Mount: AZEQ6
Camera: Atik One 6.0

The total exposure is around 3 hours in july 2016. As my camera is black & white i use RGB filters to build the chrominance layer, and stack several photo on each filter to maximize signal over noise.

18 photos of 5 min flitering Luminance except UV
7 photos of 5 min filtering Red
5 photos of 5 min filtering Blue
8 photos of 5 min filtering Green

I used the software Prism 10 to manage the capture, the pre-treatment (Removing offset, dark and flat). The stacking and the post-treatment was done with Pixinsight and at the end Photoshop.
