What is the diameter of the optical tube?
I would like to mount it in clamshell style rings.I just bought this ZWOptical finder-guider scope. It is a nice, simple and light-weight design, but I cannot reach focus with my Canon EOS Rebel XT DSLR. I removed the short OTA section, I used a T-mount plus 1.25″ T-thread nose-eyepiece adapter, I turned the rotating focuser all the way in, but nope, I still cannot reach focus. I need a still shorter focus OTA length, but how??? Please help!!!Question by: Felipe Orduña on Oct 17, 2015 12:43:00 AMThe 60mm finder-guider scope is designed to reach focus with a ZWO or similar autoguider camera with an optical back focus depth of ~15mm. A DSLR with T-ring requires 55mm, so you would need to remove a 40mm section of the tube in order to attach a DSLR, which may not be possible as ZWO intended this to work with their much-shorter camera.
Normally, you would want to put your DSLR on your main telescope (or use a telephoto camera lens) and then you would mount the ZWO guide scope with an autoguider camera on top or on a side-by-side plate so that the autoguider camera can correct tracking with short exposures while your DSLR is on the other telescope or lens taking long exposures.

More than likely a dovetail plate will be more than enough. You could also opt for rings. There are many different options. Knowing more specifics about your setup would be helpful.
