Following advice I just got a CA-35 adapter and wide tmount adapter for my SBIG STT8300 and FWG8 filter wheel, and a wide mount T for my nikon so I can use both with my FSQ106.
Just tried them out tonight for the first time. The nikon just makes it to focus, the focuser is all the way in except 1/4 of a turn. So that should be okay I am thinking. Unfortunately my SBIG has a slightly longer back focus than the DSLR and doesn't quite make it even with the focuser all the way in. I cannot take anything out of the image train, the CA-35 is simply too long.
I am a bit disappointed these adapters don't work. Why do TAk make the adapter so it barely covers a DSLR and is no good for CCDs with a filter wheel.
As mine is an older fsq106 and has the "captains wheel" am I able to take that out and would it help anyway given it is in front of the focuser?
If that doesn't work I will have to go back to T2 extensions and hope the vignetting isn't too bad unless anyone has any better ideas?
