轉接器，3.5″ Hedrick Focuser 至 2.7″ AP Threads

The machining is precise—the threads on this adapter mate perfectly with my AP gear without any wobble. It solved a frustrating connection issue I’d been dealing with for weeks.

Bolted it on to my 3.5″ focuser and the female AP threads lined up perfectly—zero wobble, just a snug, solid connection. Now my AP accessories drop right in with no fuss.

I was a bit worried about thread compatibility, but this adapter threaded onto my focuser and accepted the AP accessories without any binding. The PDF drawing made it easy to confirm the dimensions before ordering, which I appreciated.
