Meridian Telescopes

P.O. Box 571 Mt. Clemens, MI 48046-0571

Description: FOCH Helical Focuser
The primary feature of this 2" focuser is the helical action for focusing. The accurate thread cut reduces the off axis movement to a minimum through the length of travel minimizing any shift in the image when focusing. This helical 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 performance at a great value.
