This camera adapter is designed to connect DSLR cameras to telescopes with 2" (50.8mm) eyepiece tube (focuser) for digi-scoping. The adapter has a 2" external diameter on one end (to be inserted into telescope's 2" focuser) and a T2 (M42x0.75mm) thread on the other for connection to standard SLR camera T-rings (some camera T-ring are available from this store).

The adapter's length can be adjusted (in 35mm range) to accommodate the requirement of image focus by different camera models in relation to the telescopes used. 

There are two sets of internal threads on the 2" end of the adapter, so that the adapter can also connect to scopes with either M48x0.75mm or M39x1mm threads on the eyepiece or focuser base. Therefore, this adapter allows camera connection to telescopes with or without the telescope eyepiece in its place.

The 2" tube section can also be disconnected from the bigger barrel that has a male M42x0.75mm thread for camera T-rings. There are M52x1mm internal threads inside this bigger barrel section so that it can be connected to large telescopes with equivalent male threads.
