Astro-Physics 2..5" Extension Tube for AP Focusers

Astro-Physics 2.5"extension tube. Threads directly into the drawtube of the AP 2.7" focuser and into the 4" to 2.7" adapter provided with the AP 4" focuser. Has knife-edge baffles and an interior that's painted flat black to eliminate internal reflections. Typical AP top quality and in like new condition with no marks or scratches and glossy black anodized finish.  I purchased it for an AP scope that I no longer own. $48 includea U.S. shipping.

Thanks for looking!
