SBIG FW8G-STT adapter

The threads are perfectly machined, so the adapter locked onto my filter wheel without any wobble. I was able to get it aligned and installed in just a few minutes, and now my imaging train feels solid.

The alignment pins fit snugly into the filter wheel's slots, making installation quick and secure. I had no play or tilt once everything was tightened down.

Threads on perfectly the first time—no shimming needed, which is rare for adapters in this hobby. The machining is clean and it mates the FW8G to my guider without any play. Solid buy if you're tired of fiddling with spacers.
