APM 2,5" Deluxe Focuser with new centering eyepiece clamp and adapter

APM-Telescopes use now since more then 10 years the worldfamous, worldbest Focusers from Starlight Instruments/USA. Such extremequality 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 Imagers we designed a new rock solid focuser operating ultrasmooth.

Based on our first ZTA focuser now we developed a new improved version with self centering eyepiece clamps. Also the adapter from 2" to 1.25" has the new self centering clamp like in our Deluxe eyepiece adapter. This new model has a focuser travel of 92 mm. The whole focuser is 360° rotatable.
