Camera adaptor T2 ring for Canon EOS with limited optical length

With this accessory, you can adapt the camera bayonet of a system camera, e.g. a single-lens reflex camera (DSLR), to the T2 thread (M42x0.75).

There are several ways to connect the camera to the telescope with the T2 ring: What almost always works is to use a 2" plug-in sleeve with a T2 thread. A screw connection is of course even better. To do this, the focuser of the telescope must have a T2 thread. If it does not, another adaptor can be used to convert the thread of the focuser to T2.

This T2 has an especially low optical length. This makes sense when the camera sensor cannot achieve focus with normal optical lengths of around 10mm.
