Description

This model is intended to replace the standard Crayfords, generally fitted on the standard Newton Sky-Watcher tubes with a single focus speed. This dual speed Crayford focuser achieves fine focus thanks to the 1:10 gear ratio. A very noticeable advantage during high magnification observations and image capture. It can withstand heavy loads (APN). An adjustment screw located at the bottom of the focuser maintains focus depending on the orientation of the optical tube.

A 31.75mm adapter is supplied as standard to use eyepieces of the same size from the 50.8mm exit. The 31.75mm slide on the adapter can be unscrewed to secure a T2 ring. The 50.8mm outlet can also be unscrewed from the tube to be replaced by an M54x1 female threaded fitting. A 50.8mm extension tube is also supplied.

This focuser is also suitable for DIY telescope projects.

Hole center distance: 85 x 85mm. Stroke length: 115mm.

CAUTION: It does not work for Newton f / 4.
