2" Crayford focuser for Newtonian telescopes

This focuser offers best value for your money. It runs very smooth even under high load up to 2.5 kg.

Compared with simple rack & pinion focusers, the "Foc N2" is a real improvement.

Many amateur astronomers use this focuser to retrofit their telescopes.


Mounting to the OTA:

The focuser comes with a versatile four-hole mounting plate. The horizontal bore distance is 70mm, the vertical bore distance is 72mm.

Scope of delivery:

- 2" Crayford focuser with universal adapter plate
- 2" - 1.25" reducer with brass clamping ring

TS 2 Adjusting the focuser's tension:

The knurled screw on the eyepiece side adjusts for the focuser's tension. The heavier the load is, the stronger this screw has to be engaged in order to prevent the focuser from slipping.

Fixing the position:

Astro photographers will like this feature. When the knurled screw on the telescope side is tightened, the focusing mechanism is disengaged and the drawtube is locked; thus preventing the focuser from unintended moving.
