Up for grabs is an Astro Essentials focuser compression ring attachment M54 thread. This is an excellent replacement for the stock compression ring that comes with the Sky-Watcher ED72 focuser which has two screws and mars the diagonal or any photography equipment really bad.
May also fit other scopes. See link below for more details.

Purchased from First Light Optics for GBP39 + shipping (over $75 AUD). Asking for $40 + postage at cost. Pick-up available from Sydney CBD or upper north shore by arrangement.
Only selling because the scope has long been sold, and this is surplus to my needs. Pls PM me with any questions.
