محول، فاصل منخفض الارتفاع 3.5″ من Hedrick Focuser إلى SecureFit

Exactly the 1/2 inch of extra back focus I needed to clear the filter wheel—the machining is precise and threads mate perfectly with my focuser. No flex or tilt detected even with a hefty camera setup attached.

Finally got the spacing dialed in with this adapter — that extra half inch of back focus made all the difference for my imaging train. The low profile design fits perfectly between my focuser and spacer without adding unnecessary bulk. My stars are finally sharp corner to corner now.

Installed this between my Hedrick focuser and camera to dial in the spacing — the 1/2 inch back focus was spot on. Machining is clean and threads engaged smoothly right out of the box.
