These adapters take advantage of the 55 mm spacing distance standard that is being offered by the popular ZWO and QHY camera systems.

These adapters are designed to provide the proper spacing distance required between the 92FF field flattener or 92TCC telecompressor corrector and the camera sensors when using those company’s 55 mm camera spacing standard. Choose the adapter that matches the thread size on the scope-side of your camera setup and you are all set to start imaging. 

A mono camera that is using a filter wheel with 3 mm thick filters may require the addition of a 1 mm spacer ring.  The spacer ring is available through Precise Parts.

Elizabeth F. ★★★★★

Finally, a simple solution for getting the proper 55mm spacing with my camera—threaded on cleanly and snug right out of the box. The machining is precise enough that I didn't have to mess with shims or spacers to hit focus.

Isabella ★★★★★

Screwed this onto my Stowaway's 2.7" threads and the backspacing landed right at the 55mm mark my ASI camera needs. Threads felt clean going on, no wobble or cross-threading. One less thing to fiddle with during a session.

Joshua ★★★★★

Finally got my rig to exactly 55mm without stacking a bunch of thin spacers, and the backfocus looks perfect on my ZWO. Threads onto the 2.7" side cleanly with no play.
