Heavy-DutyT-2 Quick Changer (BP6A)

Finally, no more fighting with threads in the dark. The bayonet lock clicks into place with a satisfying, solid feel. Took maybe 10 seconds to swap out my filter wheel tonight.

Switching from a screw-on adapter to this quick changer shaved off so much time during my imaging sessions with such secure locking. The bayonet mechanism feels rock solid under the weight of my filter wheel and camera.

The bayonet lock is incredibly precise and firm, no wobble at all when switching between my camera and eyepiece. Makes swapping gear in the dark much less of a fumble than my old screw-type setup.
