Has anyone found something useful for correcting a CC6 (GSO, Omegon …) ?

 

What would be the most appropriate field corrector ?

I don't see the point

I don't see the point

Why not?

Interested in deep sky imaging? Eh…you might want to look elsewhere.  The scope’s long f/12 focal ratio and the lack of dedicated field flatteners or coma correctors make it less than ideal for capturing the dim stuff

The above from Ed Tings review.

 

if not ’dedicated’ so some user created solution ?

 

f12 is of course limiting, but has any owner tried any correctors or reducers ?

That was interesting, I will search more.

Why not?

The CC has a well corrected field, much better than a C9. And for the C9 I can't find a point for correction neither.
It's catoptic and no frac. When I'm after lenses I'm getting a frac.

Much easier to use on an SCT or mirror-focusing Mak because of their greater focus range.  Fixed focuser scopes are much harder to adapt.
