TeleVue'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.
