Low profile telescope focuser
I made this thing so I could get my Canon EOS camera into prime focus on my dinky little telescope. The original focuser body was too long, so I made a shorter version that the original focuser tube and gears could fit into. I also used an adapter for the camera that I got from the thingiverse to connect the camera to the focuser tube. BTW, the diameter of the focuser tube is quite odd. Its Outer Diameter is 32 mm which is about 1.25" but that doesn't mean it takes a 1.25" lens. (Its inner diameter would have to be 32mm for that) so it doesn't match the 1.25" or 2" lens-mount standards on most telescopes. It just so happens that the EOS camera adapter I used slotted perfectly onto it. (See http://www.thingiverse.com/thing:10829 for info)
