2" Crayford focuser with 1:10 transmission, for refractors

Solid, ball-beared focuser for ATM or upgrading refractors with simple focusers. The main characteristic is a very smooth operation.

Load capability:
The focuser accepts payload up to ca. 2.5 kg. So it is also suitable for havier cameras and accessories.

Adjustment:
The knurled screw on the eyepiece side adjusts for the drawtube's resitance - the more it is tightened, the heavier loads can be held without slipping.

The knurled screw on the telescope side fixes the drawtube when tightened. This is useful for astro photography.

The micro transmission
The focuser has a 1:10 micro transmission allowing very fine adjustments. Turning the micrometre screw by 10° moves the drawtube by only 0.038mm!

Telescope side adaptations:

The focuser has a telescope side inner diameter of 72mm. An adaptor from 72 to 86mm inner diamter is included. This fits e.g. to Skywatcher 80 + 90mm refractors and Celestron 80mm refractors.

Further adaptation possibilities:

In the "recommended accessories" section, we offer adapters for Skywatcher ED refractors and all Skywatcher and Celestron achromatic models. If you want an individual solution, please don't hesitate to drop us some lines. We will then make an individual offer for you!

Mechanical heigth:

The focuser's minimum height is 75.5mm - measured from the 2" end to the 72mm telescope adapter. The 72 to 86mm adapter has additonal 17mm.

Focus range:
The drawtube's travel is 74mm. So you have a wide back focus range.

Scope of delivery:

-- 2" Crayford focuser with 1:10 micro transmission
-- Universal adapter to 86mm (male)
-- Reducer 2" - 1.25" with brass clamping ring and M48 filter thread
