FLI PRO Line 轉 FSQ/Sky90 轉接環 (TCD0018FLI-1)

Finally convinced my Sky90 to play nice with the FLI filter wheel—the threading seats perfectly flush, no tilt or wobble when I rack focus. Took maybe two minutes to swap out my old spacer, and the whole imaging train feels rock solid now.

The threads on this adapter are machined perfectly—my FLI filter wheel screws onto the Sky90 without any wobble. It feels solid and well-made, exactly what you need for precise astrophotography.

Finally, a solid adapter that lets me attach my filter wheel to the Sky90 without any wobble or alignment issues. The threading is precise and smooth, so no more struggling to get everything square.
