Re: M45 Pleiades - Failure
the Bresser has nice pin-sharp images of the stars in the eyepiece. Then, after attaching the Zwo I adjusted Sharpcap setting Swapping the eyepiece for the camera can result in a shift of the image and potentially being off-target.

The Skywatcher 127 MAK is f/11 with a focal length of 1500mm - which helps with lunar/planetary/solar. I also have a Celestron C8 which is f/10 with focal length 2032mm which is better still providing the seeing is good. I have never had any experience with Dobs.

Re: 73% waxing moon, Clavius, 3 different cameras
Thanks Tim. I hope to revisit this using my Celestron C8. The 127 MAK does very well for a budget scope.
