Borg #7427 Helicoid T Helical focuser. Comes with Borg #7424 M57/60 adapter that allows it to screw onto the back threads of most Meade and Celestron SCTs.Use your focus knob for coarse focus, and the Helical T allows approximately 1" of helical travel to end the image shift problem. Now when you focus at high power that image will stay still. It takes up only 2" fully closed and 3" fully opened. Alternative to Crayford style. Has Borg #7506 holder for 2" eyepieces (you would need Borg adapter #7317 for 1-1/4"). Nice and smooth motion. $157 plus shipping new, I'll sell for $100 shipped. Pictures on request or go to Hutech's website for more info. Money order please.
