Baader M48 extension tube 5 mm

Baader M48 extension tube 5 mm

Description

The Baader M48 extension tube 5 mm is designed to adjust the working distance of modern cameras and accessories with M48 threading. It ensures accurate backfocus spacing and optimal optical performance in astrophotographic setups.

It features an internal M48 female thread (3.5 mm depth) on the telescope side and an external M48 male thread (3 mm depth) on the eyepiece or camera side. With a 5 mm optical path, a 45 mm clear aperture, and a 53 mm outer diameter, it integrates seamlessly into M48 systems.

Manufactured from high-quality aluminium, the adapter is lightweight (0.01 kg) and durable. Unlike the older T-2 standard with 5 mm thread depth, this tube uses the modern 3 mm standard to accommodate the extremely short optical height of new-generation cameras.

Part of Baader’s M48 adapter family, this extension tube is an essential accessory for precise optical spacing in astrophotography.
