SW Newtonian, ATIK 314L+ and Baader MPCC

Hi,

I hope that it's correct section to clarify something:

To eliminate coma in SkyWatcher Newtonian reflector (f/4), for astrophotography purposes, I'd like to use Baader MPCC coma corrector. For imaging I'm going to use ATIK 314Lplus CCD (without filter wheel). Space between CCD and MPCC should be equal to 55mm, to avoid vignetting. In this camera focus distance from CCD to the T2 thread back end is equal to 10.1mm, so I need some 45mm long spacer/extension. And now there are two questions:

1. Am I right? :)
2. Is in the Baader MPCC Mk-III Photo-Visual set included such 'extension ring'?
If not:
3. How to keep required distance between CCD and MPCC?

Cheers,
Piotr

Hmm, I guess no one has an answer! You should maybe try one of the UK forums such as stargazers lounge or astronomyshed, you'll get lots of advice and info there.

The ukastroimaging website is good for such a specific question...
