M63x1 Connection Adapter for TSFLAT2,5 and M63 Reversion Adapter

The adapter has a male M63x1 thread at both sides. Both threads are separated by a 1 mm thin strip.

Amongst other uses, the adapter allows the direct connection of the 2.5" PHOTOLINE corrector for APO refractors to focusers with female M63x1 thread, like the 2.5" Starlight Feather Touch focusers or the modern 2.5" rack and pinion focusers from TS.
