Isabella J. ★★★★★

Finally, a solid replacement for that finicky stock focuser — the thread engagement is buttery smooth and it mates to the Optec unit without any play. Night-and-day difference for keeping my framing locked in during a long exposure run.

Steven R. ★★★★★

The machining on this adapter is incredibly precise—it threads onto my Epsilon 180 perfectly with zero play. I had the Gemini mounted and collimated in under ten minutes.

Natalie ★★★★★

I was worried about compatibility with my setup, but the mounting holes lined up perfectly with the Gemini unit. The machining feels precise and solid, and it eliminated the play I had with the original focuser.
