We developed the APQ Tube Rings 218 especially for the APQ 200/1600 Fluorite Quadruplet Polychromat.

Due to the identical spacing of the fastening screws of 88mm, the APQ Tube Rings 218 are compatible with all APQ Dovetail Plates.

Thanks to the swivel joint, the tube rings can be folded open or closed. The tube rings are closed with a knurled nut made of stainless steel.

The telescope can be easily connected to the mount or disconnected again.
