asi1600 11mm black ring

carlos fuentes

Hello,

I want to remove the 11mm black ring from my ASI 1600MM camera to place it on the EFW Filter Wheel but I can't. I don't see any tightening screw. I tried to turn the ring with tongs but it is impossible and I think I can damage the camera.

Can you help me ??
