Olivia G. ★★★★★ Oct 21, 2026

The bolt pattern matched my existing holes exactly, so installation took less than five minutes. It feels solid and heavy, which gives me confidence for the focuser upgrade.

Emily ★★★★★ Oct 20, 2026

Dropped in perfectly to my old C8, the custom-machined bolt pattern lined up without any fuss. Now my focuser upgrade feels rock solid and precise.

Richard F. ★★★★★ Oct 19, 2026

The custom machining matched my telescope's bolt pattern perfectly, so the focuser base slid into place without any extra drilling. Installation took under five minutes and feels rock solid now.
