This threaded adapter ring replaces the 1.25" eyepiece holder on the TeleVue Powermate 2.5X 1.25" (and other 1.25" Powermates). The adapter threads directly onto the chrome barrel in place of the eyepiece holder.

The 48mm T-Adapter is the accessory of choice if you’d like to attach your full frame DSLR or astronomical camera to a Celestron EdgeHD optical tube.
