Yes but judging from the wonderful full frame CMOS images on that setup on Astrobin it would be worth the effort.
I must admit I never thought a Celestron product would produce such high end images.
Focuser shift may be another issue.

Are the Rassa's difficult to use?
At the crazy low f numbers is finding/maintaining focus difficult? What cameras have proven themselves on the Rassa's (spacing issues discussed)
Id love to hear from owners of Rassa's..... Would they purchase another Rassa or are the fininiky machinations of such low f numbers too difficult for mere mortals (yours truly)?
Currently I'm using a 130mm f7 APO triplet, no fuss, simple point and shoot, hence my concerns with the Rassa's .....
Your thoughts please.
