Feather Touch 調焦座專用低輪廓光學背板 (DCQFT3)

Threading this onto my SVQ100 was a breeze, and the low profile design finally lets my camera sensor sit at the perfect distance from the focuser. The anodized finish matches the rest of the setup well and feels solid.

Finally, a visual back that doesn't add an inch of unnecessary length to my optical train. The low profile design threaded on perfectly to my Feather Touch focuser, and the lack of slop in the connection gives me confidence my imaging train is solid.

The slim profile is exactly what I needed to get the right spacing for my AP setup, and the threads engage smoothly without any slop. It makes connecting my camera a breeze compared to the stock adapter.
