APM 3" Rack and Pinion Focuser

APM-Telescopes use now since more then 10 years the worldfamous, worldbest Focusers from Starlight Instruments/USA. Such extreme quality has its price.

To be able to compete with other manufacturers APM-Telescopes decided to create together with scilled Amateurs his own Series of high end focusers, which comes very close in the quality to Starlight, but at a much lower price level. Regards tube connection we oriented us at Starlight to be able to switch and upgrade without additional adapters to Starlight focusers. At the focuser-end we choosed to use todays standard threads of available accessories like Field Flatteneres and Reducer/Flatteners, to save you money purchasing expensive adapters. Together with Images we designed a new rock solid focuser operating ultrasmooth. Our focusers does not use ballbearing supports which tend to tilt, our focusers using telfon support which guarantee a complete lack of play due heavy loading.

Our second model offered here, has a focuser travel of 114 mm, later on we introduce the same focuser with shorter focuse travel to use with R.C., SC, ACF and Newtonian Telescopes. Optional APM-Telescopes offers custommade 360° rotation adapters for your specific telescope.
