Baader M54 Extension Tube 7.5 mm

This Baader extension adds 7.5 mm of optical length to an M54 threaded imaging train. It provides an M54 × 0.75 female telescope-side connection and an M54 × 0.75 male camera-side connection.

Thread and clearance dimensions

The female thread is 3.5 mm deep and the male thread is 3 mm long. The manufacturer lists a 51 mm inner diameter and 59 mm outer diameter. The 7.5 mm extension is the added optical spacing, rather than the overall dimension including the male thread.

Spacing applications

The aluminium extension provides a fixed spacing increment between compatible cameras, reducers, flatteners and other threaded accessories. Combine it with the model-specific adapter arrangement required by the optical corrector.
