The focuser is the biggest problem with them from what I understand... The reflections shown in the images on CN happen in newts and SCT's too.. its generally a reflection of the primary in the secondary.. I've seen it with plenty of different optical systems.

The sagging focuser is an issue, but its easily sorted out... a 3" Feathertouch will hole absolutely any load you throw at it, and considering the price of the scope in comparison to other 10" RC scopes, you're looking at $4600 with a 3" FT... If you flocked the 2ndry and whacked on a good focuser you could be looking at a very nice scope...

Take Paul Haese's 8" GSO RC... His had reflection issues and focuser issues when he got it... it's now producing epic images with the scope just from a new focuser and flocking.. The revised 8" had a baffle that does not need baffling, however the focuser on the revised scope is still not capable of holding a serious camera setup.. for a DSLR it might be fine, but for a mono CCD, filter wheel and an OAG the focuser is horribly inadequate.. Having said that, most consumer scopes have average focusers that are not capable of holding a big imaging setup, the fact is that on a short focal length scope the affects are nowhere near as noticeable as they are with these longer focal length scopes.
