The camera rotator allows for rotation of a camera/lens setup at any angle about its optical axis and is much more stable than the typical ball-head mount which disturbs the system balance (especially on light-weight portable mounts) and is susceptible to slipping.
The rotator is convenient for switching between landscape and portrait camera orientation, as well as any arbitrary angle, such as when a camera is mounted on an equatorial tracking mount and a level horizon is desired.

The distance between the camera mounting plate and the rotation axis is 43mm. Two spacers are included which widen the camera plate and the mount plate, or raise the camera plate for small body cameras such as mirror-less cameras.
Additional accessories include a plate and secondary rings for piggy-back mounting of a second camera, guide camera, or finder.
