Focusers

A masterpiece of engineering and workmanship, JMI Standard Event Horizon Telescope Focuser - Newtonian is a low-profile, friction-drive focuser designed for both the amateur and professional telescope market.

Takahashi micro edge focuser 1/7 MEF-3 to suit the below range of telescopes. Add this 1/7th micro edge to your 2.6" or 2.7" focuser for much finer focusing

The highly acclaimed Crayford design uses high pressure on a metal drive shaft pressing against a 2.5" metal drawtube which is held by bearings on the opposing side.

The new CHL 2.5” large format focuser features a low profile hybrid design to allow focal reducers to be used inside the focuser.

ESATTO is the new generation robotic focuser that includes motor and advanced electronics and you control with EAGLE or any Windows computer by connecting it to a USB port, or via WiFi by using the Virtual HandPad on your smartphone or tablet!

ESATTO robotic microfocuser is also available in a larger 3" version: 76mm free aperture, 25mm of draw tube travel, 8kg of payload capacity and an incredible resolution of 0,04 micron per step!

The ESATTO 4" is the large dimensions robotic microfocuser that we designed for observatory class telescopes or for astrographs that need for large free aperture, like the Takahashi FSQ-106.
