89mm Prime Focus Ring (TKA86002)

Finally got this ring threaded onto my OTA and the fit is absolutely perfect — no wobble at all. The anodized finish feels premium and slides into the focuser smoothly. My test shots came out noticeably sharper.

Threads on smoothly with no play at all, which matters a lot when you're trying to keep a camera sensor perfectly square to the optical axis. Snapped into my imaging train and held collimation all night. Exactly the solid connection I needed for prime focus work.

Threaded onto my focuser without a hint of play, which is exactly what I needed for prime focus imaging. The 89mm size matched my tube perfectly and my stars are finally round corner to corner. Solid machining, no flex even with the camera hanging off it.
