Good question. Was in such a rush to play with it that I made a small platform with an old guide scope and another old refractor (80mm/F6). Think I assumed not enough back focus after fitting a rotator and filter holder But I'm wrong. Just checked and have about 74mm backfocus so it's not only possible but will be done shortly. The guider might be a problem but I've got an unusual focuser that can go a lot closer to the ONAG so it might work.Thanks for the wake up call.
Cheers Stephen
