Geoff, you've got the one with the autoguider interface??. Bintel are now stocking them, or will be shortly.
Yes. it has a pick-off prism just in front of the filter wheel. Since the whole thing (off axis guider, filter wheel) is integrated into the camera body, the prism is quite big, so there shoulldn't be any problem finding guidestars. I have only had it out on two nights so I don't know if there will ever be a problem, but when I tried it there were always suitable guidestars in the field of my Orion Starshoot autoguider.
I didn't want to wait for Bintel to get their stuff in, but the price they were quoting was pretty much the same as I paid by getting it direct, so I would have bought it from them if they had something on the shelf.
Geoff
