#64 and #64ST T-Adapters: The basic means of photography through any ETX Astro Telescope or Spotting Scope, the T-Adapter threads to the rear cell of the telescope, followed by a T-mount appropriate to the user's brand of 35mm camera. In this way the camera body is rigidly coupled to the telescope's optical system, which in effect becomes the camera's lens. #64: for ETX-90EC, -105EC, -125EC. #64ST: for ETX-70AT.
