FS-60C 減焦及平場用 25mm 間隔環 (TCD0025)

Finally got the spacing dialed in for my SBIG camera without the filter wheel. This 25mm spacer threads smoothly and locks up solid, no wobble at all. Exactly what the FS-60C reducer needed for crisp stars corner to corner.

Threaded perfectly onto the FS-60C reducer, and the 25mm depth put my SBIG camera at exactly the right back focus. Solid machining with no play, and the spacing is spot-on for the Single Shot setup.

Screwed this between my reducer and the camera and the spacing came out dead on 25mm, stars are round to the corners now. Machined threads felt clean going on, no grit or wobble.
