Astro-Physics 3.5" Rotating Focuser Accessory Adapter
This is a focuser endcap and adapter that is required for TEC refractors to use the QUADTCC Telecompressor. It threads into TEC Focusers. This endcap screws onto the focuser drawtube and can be locked into place using three set screws that are found in the endcap’s surface (this is an optional action that imagers may want to use). The endcap terminates in a 3.5” circular dovetail which ensures absolute orthogonality for your imaging needs and allows you to quickly swap accessories or cameras.
