For this image of the Orion, Horse and M78 I was basically testing my SVB CLP Filter, Astronomic 12nm Filter, and my 135mm Samyang. I battled cloud, full close moon, and heavy LP to get this result. Its about 1 hour RGB, and 1.5 hour Ha. 60 sec subs on a Skywatcher pro. I used dithering for the RGB and it was way less noisy than the Ha.
