Hi there.
This is the 3" version with a heavy payload capability and excellent resolution.

A field rotator can be used on its own for field derotation on altaz mounts (e.g Planewave L mounts), or in conjunction with a camera for object framing/guide star selection.
It comes with an adapter for either side of the rotator. On the camera side, an STL11K (bolted) adapter, and on the telescope side an adapter to bolt directly to a Bellepheron focuser (If you are interested in the Bellepheron also, PM me for package price). Obviously any number of adapters are available from Optec.
These are $3599 AUD new....Sale price $2150.)
cheers
Martin
