I'm pretty happy with how Saturn turned out. I think I can claim that the polar hexagon shows straight sides, which is a definite improvement over the dark blobs I was able to get with the 6" previously.

Looks great Andrew ..I have a CPC 925 and its great on the Planets better than my 130mm Apo triplet , of course wipes out my new 60mm Tak at 200x , I had the CPC 925 at 500x on Saturn one great night...Soo much detail the 130mm Apo Slightly sharper on an average night!
These scopes were said anecdotally , to be designed by Vixen opticians when they had a relationship with Celestron ..a different format from the usual SCT with a much flatter field and high strehls, and on average sharper IMO...Enjoy!
