Sorry the scope is a Skywatcher collapsable DOB, the picture is the 2" adaptor from the scope. I really want to shorten that adaptor (I could get a hacksaw) and wasn't sure if the
Lumicon from Myastro Shop had the same wedge shape as my adaptor. Doing this will acheive prime focus better for the DOB but 1" which does not have a lot of travel left with the webcam I am using.
