適用於 ASI 冷卻相機的新型固定環 (78mm 直徑)

Finally, no more light leaks around the camera adapter—this ring fits my cooled camera body snugly with zero wobble. The 78mm diameter is exactly what I needed for my imaging train.

Woke up to a perfectly round star field on my first night out with this ring—the 78mm bore holds my ASI533 Pro snug with zero tilt or sag, even when the scope's pointed near the zenith. Threads engage smoothly, and it's thin enough that I didn't have to rebalance the whole setup.

The fit on my ASI294 is absolutely perfect—no wobble or play at all. The anodized finish feels quality and the threads engage smoothly. Definitely solved the alignment issues I was having with a cheaper ring.
