Avery ★★★★★ Oct 20, 2026

Screwed this onto my APM 152 and the fit is absolutely flush with zero play, the aluminum finish matches the scope's aesthetic perfectly. The threads engage smoothly and my Feather Touch locks up rock solid, so collimation holds through a whole night of observing.

Mia ★★★★★ Oct 19, 2026

The machining on this adapter is precise—it fits my APM 152 without any wobble, and the aluminum finish matches the focuser perfectly. Installation took under five minutes, and now focusing is noticeably smoother than with the stock setup.

Richard G. ★★★★★ Oct 18, 2026

I was pleasantly surprised by how smoothly the adapter slides into place on my APM 152—the fit is precise without being overly tight. The black anodized finish matches the rest of my setup perfectly and feels durable.
