Optec-DSI 3.5x24tpi 轉 OPTEC-2400 (19910)

Threaded on perfectly to my focuser and the dovetail side mated cleanly to the camera holder, no wobble at all. The machining is precise enough that I didn't have to shim anything, which saved me a whole imaging session.

Had a bit of trouble at first figuring out which thread goes where, but once I matched the 3.5x24tpi to my focuser it threaded on perfectly and the OPTEC-2400 end locked solid into my gear. The machining feels precise and it eliminated a slight wobble I was getting with a previous adapter.

Screwed this onto my focuser drawtube and the 3.5x24tpi threads caught cleanly on the first turn, no cross-threading at all. The OPTEC-2400 dovetail side mated with my existing camera adapter without any wobble. Solid machined piece that finally let me swap between my two imaging trains.
