More Info

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 Variable Tele-Extender is an adjustable-length cylinder that provides a variable range of projection magnifications for a given eyepiece.

Note: The Variable Tele-Extender does not work with the Meade ETX-90 telescope.

Some 1.25" telescope eyepieces have housings that are too wide to fit inside the tele-extenders. The following Orion telescope eyepiece series are recommended for use with Orion tele-extenders:

  • Orion Explorer II
  • Orion Sirius Plossl (except 32mm and 40mm)
  • Orion HighLight Plossls (except 32mm and 40mm)
  • Orion Ultrascopic (except 30mm and 35mm)

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!
