محول حلقة T من Tele Vue لـ 2" 4x Powermate - PTR-4201

The threads mate up cleanly with my 2" 4x Powermate, and the lock ring feels solid once seated—no wobble when I tighten it down for imaging sessions. It's a simple piece, but it does exactly what it's supposed to, and that's all I needed.

Switching to a mirrorless camera body required an adapter, and this one threaded onto the 2" Powermate without any wobble, letting me reach focus on deep-sky targets. The brass compression ring holds my camera T-ring firmly, which is a huge relief for long exposures.

Screws onto the 2" 4x Powermate without any wobble, and the threads are buttery smooth. I got crisp, round stars across the whole frame on my first test shot.
