TCF-Leo Low Profile Focuser

The 3-inch profile is incredibly slim for a focuser this solid—I had just enough room in my imaging train. It locks onto my setup without any noticeable flexure, which makes fine-tuning focus much easier than my old unit. Definitely worth the upgrade for anyone squeezed on back-focus distance.

I was worried about clearance with my imaging train, but this focuser's profile is so thin it gave me back almost two inches of spacing. The 3-inch opening handles my wide-field setup without any vignetting, and the focus action is butter-smooth right out of the box.

The build quality on this 3-inch focuser is incredible—it feels solid without adding any extra length to my setup. I was able to dial in sharp focus on my CCD camera immediately, and the low profile design really saved me precious back-focus space.
