TS-Optics Adapter from M68 to M48 with 2" Filter Thread - short design

The short adapter enables the connection of adapters with M48x0.75 filter thread to focusers and adapters with M68x1 internal thread.

• Thread telescope side: M68x1 external thread - length 3.7 mm
• Thread camera side: M48x0.75 (2" filter) external thread - length 4 mm
• Additional female 2" filter thread on the telescope side, for connection of 2" mounted filters
• No effective optical length because the M68x1 external thread is completely countersunk in the focuser - a shorter adaptation is not possible
