TS Adapter from 2" to T-2 with 40mm Optical Length
TS FA240 Adapter 2" to male T2 with 40mm optical length
The TSFA240 fits into 2" focusers and has a male T2 thread on the camera side. So you can connect nearly any camera via the T2 system. The T2 thread (M42x0.75 mm) is the connection to bayonet rings to all common SLR cameras (You would also need a camera specific T-ring, too).
40mm additional optical length
Many telecopes have their focal plane beyond the focuser's maximum travel. They are intended for the use of a 2" diagonal and need an extension if a camera is used. The TSFA240 contains a 40mm extension and so you can focus without the need of an additional adapter.
2" filter thread
On its base, the adapter has a M48 thread that accepts standard 2" filters.
The safety groove prevents the accessories from falling out if the locking screw is accidentally loosened. This improves the safety of your equipment.
