That is very impressive Bert. Those stars are nice and round in the corners and the streaky ones are just polar alignment a bit off plus autoguiding a bit off. No big deal. So your scope is corrected further out than they specifiy. That's a nice bonus.
A lot of detail showing up for short exposures.
By the way it may pay to simply do Ha 2x2. I usually do that on the CDK17, but then I suppose it has a lot of aperture. You don't lose much with 2x2 but there is a big gain in the signal to noise. Its worth trying.
That's a very exciting result and a very good choice of target.
RH200 now on my possible to get list! These Riccardi Honders scopes are amazing.
