This is a setup that I have previously used with a QHY600 but it has been sitting unused in its original packaging for a while. As it stands, it is not something I'm likely to be using again; not changing telescopes again in the foreseeable future and it doesn't have the back focus.
Includes the SC-3 Short & AO-X bundle that contains all of the screws and bits to connect the two together; can be attached onto some of the SBIG cameras without the need of any adapters.
Included will be two adapters I had made for sandwiching this setup between a FLI Atlas focuser and FLI CFW 2-7. Useful if you happen to have those two components, albeit unlikely!
It did work exceptionally well while I was using it. As a note, the SC-3 is the short version meaning it is better suited for cameras with less backfocus (most cameras except for the FLI CCD's but it should be fine on their CMOS range).
