Tele Vue 3.5インチ エクステンションチューブ - X3C-0009

Slid right into my telescope’s drawtube, and the extra 3.5 inches was exactly what I needed to finally nail focus on Saturn’s rings. The build quality is solid and precise, just like I’ve come to expect from high-end accessories, and it threads on smoothly every time.

I was having trouble reaching focus with my binoviewer setup, and this 3.5" tube instantly fixed that issue. It threads on smoothly and feels solidly machined, no wobble at all. Makes viewing Jupiter and Saturn a much more comfortable experience.

The 3.5-inch length gives me just enough reach to nail focus on my refractor, and the fit is snug without any wobble at the eyepiece. I’ve been using it on clear nights for a week now, and it’s made dialing in on planets noticeably smoother.
