E180 COL Disk (TCE0180)

Finally got this mounted on my setup and the fit is perfectly snug, no wobble at all. It makes dialing in precise focus adjustments for deep-sky shots noticeably smoother than my old adapter.

The alignment markings on this disk are crisp and precise, making it easy to center my field of view during setup. It fits perfectly on my OTA and feels solidly machined. Really cleaned up my framing workflow.

Installing this disk was surprisingly straightforward, and the precision machining is obvious when you see how perfectly it mates with the telescope. The fit is snug enough that I don't worry about alignment drifting during a long imaging session.
