A very good image. I had no attention on the stars when I viewed the image. But star elongation in one corner may be indicative of focuser sag. Newts are a bit funny that way in the sense of all that gear hanging off the focuser which is at 90 degrees to the tube. Must put more leveraged pressure on the focuser.
The image though seems to lack a bit of punch/impact. I think the data is there though. The central blue neb stars could benefit from a bit of lassoed curves or shadows/highlights and the dust areas a bit more smoothing to reduce the graininess. And more colour contrast or saturation. As I say a technically very good image but to me just lacks that extra kick that it could. Perhaps the colours channels need more.
I am leaning myself to abandon binned colour and do unbinned colour and combine them in the lum channel as well for extra clarity. I was surprised at the difference between unbinned and binned data using an FSQED and reducer. Perhaps the faster the optics the more unbinned data loses clarity and resolution.
