Michael ★★★★★ Oct 21, 2026

Finally got the NP127is mounted on my OPTEC-3600 with zero wobble — the threads are precise and engage smoothly right out of the box. This little adapter is exactly what I needed for a rock-solid imaging train.

Finally got this adapter to connect my NP127is to the OPTEC focuser and it locks up solid with zero play. The 3.75" threads are machined so precisely that the tube screws on smoothly without any binding. Exactly what I needed to eliminate flexure in my imaging train.

The threading matched perfectly with my setup, and the adapter feels much more rigid than my previous solution. It's a precise fit that eliminates any wobble during long exposures.
