DESC: Meade #64 T-Adapter: The basic means of photography through any ETX 90/105/125 Astro Telescope or Spotting Scope, (for ETX 70 use #64ST Adapter) 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.
