To take this photo i used the following setup:
Scope: Newton Skywatcher 200/1000
Mount: AZEQ6
Camera: Atik One 6.0

The total exposure is around 8 hours over 1 night in august 2016. As my camera is black & white i use bicolor palette by stacking and mapping to RGB a combination of:

8 photos of 20 min flitering around Ha ray of Hydrogen
8 photos of 20 min filtering around OIII ray of Oxygen

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.
