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-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!
