2" Telescope Focuser (Compression Ring + Adapter)

A Maker World first! (As far as I can tell). I looked long and hard for something like this, but nothing suited my needs, so I designed my own. There are some good Crayford designs on the web, but require lots of hardware I didn't have. Here we have a 2" rack and pinion telescope focuser for Newtonian reflectors, complete with a 2" to 1.25" eyepiece adapter, AND with compression ring locking mechanisms on the drawtube and the adapter. There's an optional hole for a drawtube lock screw. At minimum height it's just under 2.5" above the outside of the tube, and it has over 2" of travel. There is a mechanism that blocks the tube from sliding out completely. Best of all, the focuser mechanism itself requires NO HARDWARE! If desired, M4 hex head screws are recommended for locking the eyepiece. The knurled lock knobs for M4 screws is another of my designs, also on Maker World. This took many iterations and lots of time! Please consider giving a boost if you lik
