Tele Vue's 1.25" Powermate T-Ring Adapter replaces the eyepiece holder of 1.25" 2.5x and 5x Televue Powermate Barlow lenses and allows users to attach a DSLR or CCD imaging camera, with a user-supplied and camera-specific T-ring, for astrophotography. It threads directly onto the chrome barrel in place of the eyepiece holder and is suited for photography with short focal length refractors.
Compatibility Determination
This T-Ring Adapter is compatible with newer Powermate models. If you have an older model, check and see if any of the lens elements stay with the black anodized barrel. Remove the anodized adapter from the chrome barrel or lower black anodized barrel. If the black anodized barrel does not contain a lens element, it accepts the Powermate T-Ring Adapter.
