Orion tele-extenders permit high-magnification "eyepiece projection" photography of the Moon and planets with a Schmidt-Cassegrain telescope. Orion tele-extenders are designed to fit all Celestron and Meade Schmidt-Cassegrain telescopes.
Made of anodized aluminum, the tele-extender fits over a 1.25" telescope eyepiece, with one end threading onto the eyepiece holder (visual back) of the telescope, the other end threading into the T-ring (sold separately) on your camera body.
This Standard Tele-Extender is a fixed-length cylinder that provides a single projection magnification depending on the focal length of the eyepiece you use. Some 1.25" telescope eyepieces have housings that are too wide to fit inside the tele-extender.
If you have a Schmidt-Cassegrain telescope, get a tele-extender and try your hand at taking awesome, high-resolution photographs of the Moon and planets!
