Telescope adapter for 645D

Hi all,

Does anyone know if it's possible, and if so, how to connect a 645D to a Celestron C4.5 reflector telescope?

Sorry, no help.

But here's a manual.

They reference 35mm. Didn't see anything about 645.

Hmm. Looks like the standard method was a T-mount, which I don't think would allow a 645 flange distance.

It's going to depend on the image circle projected by the telescope. The 645 is going to need a larger image circle to take advantage of the larger sensor, then the 135. Also, the mass of the camera is going to be much larger that the scope, mount and legs are going to have to support.
