#10 Sky 90 Coupling (DT) (TKP35001)

I’ve been using this coupling to connect my Sky 90 to a field flattener, and the fit is snug with zero play—exactly what you need for sharp images. The machining is so clean it threads on effortlessly every time.

The threads on this coupling are precision-machined—it screws onto my Sky 90 without any wobble. Makes attaching the reducer feel solid and repeatable.

Finally, a coupling that actually locks the Sky 90’s focuser tube tight without any play. The knurled collar is just grippy enough for cold, gloved fingers. Makes switching between camera and eyepiece a quick, solid action.
