2.7" thread-On Extensions for Astro-Physics
A1008-A: This extension has a net spacing distance of 2.55" (64.8 mm).
These extensions thread directly into the drawtube of the 2.7" focuser and into the 4" to 2.7" Adapter (A1024), or its shorter version (A1024-A), which fit the 4" focuser. They feature knife-edge baffles and an interior that is painted flat black to eliminate internal reflections.
Asking $50 + postage or pickup.
