Meade variable projection tele-extender model# 07348 - $25 shipped (within continental U.S.) - Good condition - In original box.
This is used for eyepiece projection photography with a Meade Schmidt-Cassegrain Telescope. One end connects to the male threads on Meade SCT 1.25" visual backs. The other end has standard T-threads to connect to your camera's T-ring. Adjustable length allows for adjusting magnification of the image without changing eyepieces. (I believe that this will connect to any brand 1.25" SCT visual back but am not positive). Please email me if there are any questions.
