Baader M54 Extension Tubes (5 / 7.5 / 10 / 15 / 30 / 40 mm)

Modern cameras are usually characterised by extremely short optical heights, in order to be able to be mounted on various telescope constructions. The old T-2 standard with 5 mm thread depth is a hindrance to this. To take care of this new development, all new Baader T-2, M48 and M54 parts are delivered with the new 3 mm standard.
