2" Schmidt Cassegrain Focuser with 1.25" reducer
Crayford focuser for Schmidt Cassegrains

The problem:

Focusing a Schmidt-Cassegrain is sometimes a problem becaus of the mirror shifting thus making sharp astro photos or critical observation tricky.

The solution:

Our SC-Focuser solves this problem. Due to the Crayford friction principle, it is absolutely free from shifting and offers very good craftmanship. It supports accessories up to ca. 4 kg.

The 360° rotation
Orientate your star diagonal or camera without loosenig locking screws. Search for a guide star with an Off-Axis-Guider without touching the camera. Just turn the knurled knob on the telescope side of the focuser and you can rotate the whole focuser with its accessories.

The drawtube locking mechanism
It disengages the focusing mechanism and holds the drawtube in place firmly. This is essential for astro photography.

Travel
The focuser's travel is ca. 25mm - this is more than enough. Coarse focusing is done with the telescope's main mirror - fine tuning is performed afterwards with the TS Crayford.

1.25" Reducer
A reducer from 2 to 1.25" with brass clamping ring and 2" filter thread is included.
