#126 2x Barlow Lens: An amplifying lens, the multi-coated #126 2x Barlow (Fig. 36) doubles the power of all eyepieces with which it is used. Insert the #126 into the telescope’s eyepiece holder first, followed by an eyepiece. Example: By itself, the 26mm eyepiece yields a power of 73X with the ETX-125PE; when used with the #126 2x Barlow Lens, this eyepiece yields 146X.

#64 T-Adapter:The basic means of photography through any ETX Astro telescope, the #64 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 cam- era's lens (see PHOTOGRAPHY, page 38).
