TeleVue T-Ring Adapter for PMT-4201 2x 2" Powermate

Both the 2x and 4x 2" powermates have a very unique feature: you can unscrew the 2" eyepiece housing (eyepiece holder barrel) and screw on a  special T-ring adapter for solid, compact attachment of CCD or camera equipment. 

You would also need a user-supplied and camera-specific T-ring for astrophotography.

The PMT-4201 T-ring Adapter threads directly onto the thread on the top of the 4x 2" Powermate in place of the eyepiece holder and is suited for photography with short focal length refractors and other optical systems.

At our observatory at 365astronomy we use a 2x 2" Powermate with this photographic T-adapter with a ZWO ASI071MC-PRO on a Celestron 11" Edge HD for imaging planets, small galaxies and planetary nebulae with success. In our configuration there is quite a level of vignetting when we take very long exposures, but it can be compensated by flats.
