Baader M54 Extension Tube 15 mm

Description

The Baader M54 Extension Tube – 15 mm is designed to fine-tune the optical backfocus between imaging equipment and telescope systems featuring M54x0.75 threading. It includes an M54x0.75 female thread on the telescope side (3.5 mm depth) and an M54x0.75 male thread on the camera side (3 mm length), offering a net optical path length of 15 mm.

Crafted from high-quality aluminum, this tube combines mechanical strength with minimal weight. It follows the updated 3 mm threading standard introduced by Baader to replace the now outdated 5 mm T-2 format. This change supports the requirements of compact modern cameras and optical setups.

Fully compatible with Baader's T-2, M48 and M54 systems, this extension tube is essential for achieving precise spacing and ensuring optimal optical performance in astrophotography and visual observation.
