محول، 2.75 بوصة Hedrick Focuser إلى خيوط AP 2.7 بوصة

Finally, a solid adapter that actually bolts directly to the Hedrick focuser—no wobble or guesswork. The female AP threads are machined perfectly, and my field flattener threads on smoothly every time.

The female AP threads on this adapter matched perfectly with my existing setup, and the bolt-on design to the Hedrick focuser was rock solid right out of the box.

After struggling with my CDK12.5's imaging train for weeks, this adapter bolted right onto the Hedrick focuser without any slop. The female Astro-Physics threads are machined clean enough that my filter wheel screws on smoothly by hand.
