The focuser fits directly onto the M90x1 thread of 6" and 1.25" eyepieces. 8" RC and Cassegrain telescopes. It supports accessories up to 6 kg and, thanks to the combination of roller bearings and rack and pinion drive, enables smooth adjustment without tilting, even under maximum load. The base on the adjustment side is flat and equipped with two M4 internal threads, allowing the mounting of a motorized focuser such as the ZWO EAF without an adapter.

Connecting to the telescope:

On the telescope side, the focuser has an M90x1 internal thread with a knurled locking nut. The thread depth is 8 mm. Using an M90 adapter, the focuser can also be connected to other telescopes, such as refractors.

Connecting camera accessories:

The focuser comes with a 2" and a 1.25" collet. An M56x0.75 external thread is available for screw-in adapters. This thread is present on both the 2" collet and directly on the drawtube.
