Thats a great comparison showing results from the 2 scopes, reflections around stars are from Astronomik filters which seem to give this with mirrored scopes as I got them with my reflector so moved to Astrodon filters so its not the wynne corrector lens group OO make causing this.
Once properly collimated stars will be better resolved, you may need software to collimate and will have to do it examining stars in the corners, took P Shah a couple of night to do his - this unfortunately is the downside of having a fast mirrored scope with very wide field CCD.
I am really pleased you got the quality you wanted and can only imagine a full image effort from a dark site - bet you've got lots of targets lined up over the Winter.
