The Variable Projection Tele-Extender for Meade LX90 and LX200. Allows for a range of effective focal ratios during eyepiece-projection photography. The Variable Projection Tele-Extender attaches to the outer-diameter threads of a Meade #07182 Eyepiece Holder (not included, standard equipment on 8-10" LX200 and 8-12" LX90) into which is inserted an eyepiece, typically in the 15mm to 32mm focal length range.
