Description: FOC1 Rack & Pinion Focuser
The primary feature of this 1.25" focuser is the low cost and light weight; only 12 ounces! The solid construction and four PTFE bearings provide a smooth action and eliminate any shift in the image when focusing. The base of the focuser body is designed to adapt to the radius of your optical tube. This rack and pinion focuser is a great option when the ATMer is considering the design of a Newtonian type telescope or as a replacement for the standard focuser on regular production telescopes. You will enjoy the great performance of this focuser at a great value.
