Once I threaded this adapter on, the reducer sat perfectly square with no wobble, and I finally got round stars across the whole frame. Installation was straightforward too, just screwed right into the stock focuser without any fuss.

My setup used to have slight tilt issues that drove me crazy during long exposures. Since installing this threaded adapter, the connection feels rock solid and my stars are nice and round across the entire frame.

Finally no more fussing with clamp ring tilt between the reducer and the focuser. The threads are clean and engage smoothly, so I'm getting perfectly round stars across the whole frame now.
