Product description

This variable extension allows you to set the exact distance you need. The adjustment range is from 17 to 23 mm. The M48x0.75 thread is the usual filter thread of the 2" filters.

The sleeve consists of three parts:

Customer reviews

Useful to optically fine-tune the 2" connections

Review by macoram on 05.05.2017 14:37:23

( 5 / 5 )

A very useful extension to fine-tune the 2" pathway between th telescope and the astrophotography gadgets. Together with T2 extensions between them and the camera we get an optically very stable but also very dynamic astrophotography chain with full control of vignetting and back-focus.
