ZWO 86mm ASI Pro 冷卻相機固定環 - RINGD-86

The threading on this ring is buttery smooth, and it locked onto my cooled camera without any wobble or play at all. I’ve swapped optics in and out a few times already, and the 86mm fit has been spot-on every single time.

I was a little worried about the fit, but the 86mm diameter matched my cooled camera perfectly and the threading is precise. It feels solid and secure once attached, which gives me confidence when carrying the whole setup outside.

The threads are machined clean enough that my cooled camera screws on straight without any wobble, and the 86mm fit is exact for the ASI Pro line. It’s a simple metal ring, but that’s all you need to keep the setup solid on the scope.
