Those I´ve had in the diagonal:
- 10, 20, 30, 40MM Pentax XW
- 55mm Tele Vue Plossl
- 25mm ES 100
- 21mm Ethos
- Several Delos
Honestly, I need to spend more time with the scope, and maybe it needs some tuning, but
with everything I've done so far, the view from my 5" refractor shows more detail, and is
not noticeably dimmer. I'm trying to like this scope and find a reason to keep it.
You're at the same point as me. I own a 6 inch CC but the issues are the same. Like how it looks, the built-in dewshield and the easy assembly, everything is plain to see. And the design in general, but:
Are you aware that your scope is just a 7.34 inch one? Mine is a 5.4. And my true 5 inch Maksutov provides more detail and contrast.
I collimated the scope with almost maximum mirror distance and since then I only need 1 inch extension with the 2 inch diagonal no matter what eyepiece. (any mm more mirror distance yields about 15 mm less focal length). And still: see if the primary mirror is fixed otherwise sharp views just come by incidence.
Maybe a better alternative would be the 180 mm Skywatcher Maksutov, when you're used to refractors and after razorsharp views on planets, moon and small objects.
Question to all 8 inch CC observers: even if the 6 mm 1.25 66° golden edge eyepieces might be sub-level to you but when you watch through it the termnator, do you also see that annoying very bright golden ring in the middle of FOV? I do and this seems to be another disease of these scopes.
