I also use a DOB tube to do webcam imagery, most webcams I am unable to acheive prime focus as the CCD element sit too far back in the camera. I use 1 webcam VAGENT the focuser has about 1mm of travel left. images done are here

I have just purchaced a DSLR 450D and wating for my T Adaptor to arrive. I found the 1.25" adaptor unscrews to expose the T-Thread so I don't need to purchace a 2 or 1.25" tube to slot in.
With that it looks like I have managed to reduce the focal length but about 1" giving a better opportunity to reach prime focus.

It's a waiting game until the EOS - T adaptor arrives
