Sky90 CFW10/ST CCD Adapter (TCD0018L)

The fit on my Sky 90 is absolutely seamless—no wobble or backfocus issues at all. It threaded on smoothly and locked the filter wheel exactly where I needed it for guiding.

The threading is incredibly precise — it threaded onto my Sky 90 without any wobble, and the CFW alignment was spot on first try. Finally, no more tilt or spacing issues in my imaging train.

Finally got my imaging train dialed in — the fit between the SBIG camera and filter wheel is rock solid with zero play, and the threads engage smoothly every time. Measured the backfocus distance and it’s spot on for my setup, so I’m getting crisp stars corner to corner now.
