Hi Ray,
I don’t actually have any 2” eye pieces. But from what I think you’re saying,
I’d have an extension tube screwed into one side of the 2” filter and either
the telescope or another piece of extension tub screwed into the other side of
the filter. That would make the filter an integral part of the weight baring
structure. I thought the metal ring for the filter might be a bit weal to hold
all of the camera’s weight but maybe not. (I tend to way over engineer load
baring structures!)
I think I’ve tracked down where the problem is. I haven’t figured out what to
do about it yet.
I think Celestron pulled a "fast one" with their T-Adapter-SC (#93633-A)
extension tube. It has an outside diameter of only 1.75”! If I look carefully
at the T-ring adapter for my EOS, it has what appears to be a reducing ring
from the standard 2” threads to the T-Adapter-SC’s 1.75” threads in it. It is
the back side of where that reducer ring is installed that I can thread my 2”
UHC filter into.
I may give Starizona a call today to find out what working options I really
have with my C6. In the meantime, I can go back to using the SL1 at prime focus
using the 1.25” adapters by removing the diagonal. At least I’ll be able to
play tonight while I figure out the 2” problem.

Michael,
I don't follow your entire letter but here is how I do it. Your Canon
adaptor has female T-thread on it. You need a 1" long adaptor that has
male T-thread on one end and female 2" threads on the other. Screw the one
end into your Canon adaptor and thread the 2" Baader filter into the other
end. The 2" end with filter fits in where the 2" eyepiece would go.
Please write me back privately and I might be able to help you with this.
