Hazel P. ★★★★★ Oct 21, 2026

The bolt holes lined up perfectly with my existing base, so I didn’t have to touch the tube at all—just screwed the insert on and attached the focuser in about ten minutes.

Victoria ★★★★★ Oct 20, 2026

That insert saved me from having to re-drill anything on my tube. The Feather Touch focuser fits perfectly into the existing base now with zero wobble, and the install was straightforward.

I was dreading having to re-drill my telescope tube, but this insert lined up perfectly with the existing holes and saved me a ton of hassle. The fit is snug and my Feather Touch focuser is rock-solid now.
