TS Optics Adapter for attaching M68 accessories to focusers and adapters with female M78x1 thread
The adapter provides the transition to the ZEISS style M68x1 connection thread, thus you can connect M68x1 accessories to these focusers.
The special feature of the adapter is a further M68x1 thread (female) at the telescope side. You can attach correctors to this thread and countersink them into the drawtube. This kind of adaption has some advantages:
You save the entire mechanicel path of the corrector or reducer and thus win valuable working distance. Often focusing is only possible through this adaption.
The lever arm at the focuser is more favourable, as the weight of the corrector is in the drawtube and thus closer to the telescope.
The adapter allows for an entirely threaded connection. Tilting, as it is possible with 2" or 3" clamping, can be excluded.
