Description

APM 3 Inch Rack and Pinion Focuser

APM 3 Inch Rack and Pinion Focuser is a rock solid refractor telescope focuser with ultra-smooth operation and travel of 114mm.  Includes camera adapters for fine focusing during astrophotography sessions.

APM created, together with skilled amateur astronomers, their own series of high end focusers, which come very close in quality to Starlight, but at a much lower price level. Tube connection is oriented to switch and upgrade to Starlight focusers without the need for additional adapters. At the focuser-end APM chose to use standard threads of available accessories like Field Flatteners and Reducer/Flatteners, to save the purchasers money instead of purchasing expensive adapters.

APM focusers does not use ball bearing supports which tend to tilt, the focusers use teflon support which guarantee a complete lack of play during heavy loading.
