The short adapter allows the connection of adapters with filter thread M48x0.75 to focusers and adapters with internal thread M68x1
♦ Telescopic side thread: External thread M68x1 - length 3.7 mm
♦ Camera side thread: M48x0.75 (2" filter) male thread - length 4 mm
♦ Additional 2" filter thread Internal thread on the telescope side, for connection of mounted 2" filters
♦ No effective optical length because the external thread M68x1 is completely sunk into the focuser; couldn't be shorter
TS M68 system adapter from male thread M68x1 to male M48
The adapter allows to connect accessories with internal thread M48x0.75 to focusers and adapters with internal thread M68x1. The adapter can be fully sunk into the M68 internal thread.
Also, the adapter on the telescope side has an internal thread for a 2" filter (M48x0.75).
For example, the adapter can be screwed directly into the focuser's M68x1 internal thread instead of the 2" barrel, allowing common adapters with an M48 internal thread, such as T-rings or off-axis guides, to be screwed on.
Screwing on adapters increases the accuracy and quality of astrophotos, since it is impossible to tilt by clamping. The adapter fits all connections with internal thread M68x1 of ZEISS level.
