Meade Tele-Extender (Pre-owned)

In eyepiece projection photography with a catadioptric telescope, you remove the star diagonal and eyepiece from your scope and insert an eyepiece directly into the telescope’s 1.25” visual back (or eyepiece holder). If your catadioptric scope did not come with a 1.25” eyepiece holder as standard equipment (such as the Meade LX200GPS scopes equipped with an electric focuser), you will have to buy one separately. The eyepiece must be locked firmly in place using the thumbscrew on your telescope’s eyepiece holder. This keeps the eyepiece from falling onto the shutter of your unprotected camera when your telescope is tilted up to the sky.

The tele-extender (a 4” to 6” tube with internal threads that fit the externally-threaded 1.25” visual back of your scope at one end and external threads for a T-ring on the other) is threaded onto the visual back, over the eyepiece. Attach your camera body, without its lens, to the tele-extender by using an optional T-ring. In this way, the eyepiece will project highly magnified images of the Moon and planets onto your film – images that are large enough to show surface detail.

With certain refractors and reflectors, the scope-specific tele-extender lens attaches to the telescope focuser’s drawtube. Your camera is connected to the lens by means of an optional T-ring.
