HyperStar フィルタースライダーアダプター

After struggling with spacing issues on other adapters, this one threaded on smoothly and held the filter slider perfectly aligned. I used it on my 11-inch scope and the shorter length made all the difference in achieving focus. Exactly what I needed for framing M81 last night.

Finally, the spacing is right—the shorter body means my camera clears the focuser knob without any awkward tilting. Threads engage smoothly and lock down solid, no wobble when I'm framing targets. Solid build for the price.

I was struggling to get my filter slider to fit properly until this adapter solved the spacing issue with my setup. The precise machining ensures a snug connection with no light leaks, making the whole rig feel more stable.
