Overall a very nice image Harel. A couple of points. The dust area looks a bit orange to me, its usually more yellowishbrown. You got the blue star forming areas really well. Better than normal. You got the jet, the dust patches all good. Your stars though need some work. They are all very fuzzy/hazy. Was there some high cloud? Perhaps exposure lengths may need to be experimented with. Its like the rings around the airy disc have too much energy in them. So that could be seeing, high cloud, focus, exposure lengths too long for the well depth, collimation perhaps, filters? Another approach would be to mask the stars out early in the processing before the stretching as they don't need as much stretching and that airy disc ring energy is getting stretched and you don't really want that. I have had this happen in some of my images with the CDK17 and a reducer and Trius 694 and occasionally with a FLI Microline 8300 with some scopes (not all). Shorter exposures is one approach but with relatively high read noise that can cost some faint areas. It may be a compromise about which is more important. What filters were these? I am wondering if the Astronomik filters are better in these types of scenarios as they have a set with higher UV correction which probably would help.
Also I wonder if its a camera issue as I have never seen this phenomena from a QSI 683 camera. It may be better tuned to the sensor than others.
