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 teflon 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.Delivery contains:
- 3" Focuser
- Adapter M78x1 OD to M74x1 OD / M68x1 ID
- Adapter M74x1 ID to 2" with brass clamp and 3 set screws
- Adapter 2" to 1 1/4"
