This superb quality female M48 to male M42 T-thread adapter from Revelation (manufactured by GSO) converts the M48 male thread found on many astronomical optical accessories like the Skywatcher focal reducers to the standard male M42 T2 thread used in the majority of DSLR T2 rings and dedicated CCD cameras. The adapter adds approximately 10mm to the optical path.

Precision CNC machined from aluminium and finished in anodised black.
