Mark,
The cool thing about the Mallincam SkyRaider family of cameras is that the back focus is only 17.5mm.? I can achieve focus and still have about 3/4" of focus travel left over.? I did not have to change anything.? Just insert the camera and start my remote dob astrophotography (after 2-star alignment and the focus exercise with the mask).??
?
My UC18 has brackets to secure the truss poles on the VMB and I did design a new set of brackets just in case that were 1" shorter.? But they were not needed so they were never built.? I designed the shorter brackets in eMachineShop.com (free cad).? With an extra set of shorter brackets, you don't have to permanently change the telescope.
