Description

The Tecnosky Precision S focuser is a rack and pinion system designed to provide high mechanical stability and precise focusing for modern astrophotography setups. This version is intended for Schmidt Cassegrain telescopes, ensuring proper mechanical integration with this optical design.

The drawtube is guided by eight ball bearings, providing excellent alignment without play or tilt even when fully extended. This mechanical design supports heavier imaging loads while maintaining consistent precision.

Focusing movement is driven by a transverse toothed bronze rack coupled with a precision pinion. Two adjustment knobs allow smooth control, complemented by a 1:10 micro reduction for fine focusing accuracy.

The focuser features an M63x1 threaded output with included adapters to M54x0.75, ensuring compatibility with a wide range of accessories and imaging trains. The total travel of this version is 2.2 cm, suitable for fine adjustment in imaging setups.

This product is offered as used. The total value with adapters is approximately 400 CHF and it is offered at 300 CHF VAT included. No additional information is available based on the provided data.
