Yesterday I got the V1 with 10-30mm and 30-110mm lenses and today I've had a very quick try-out with the Kowa 823 plus 21x and 32x eyepieces. So, some similarities with Malcolm's set-up there. I found that all combinations produced some useable results, even the long zoom with the 32x, although pics taken with this combination would probably be much better reproduced by just taking a crop of one of the shorter combinations.
I have an idea for an adapter by modifying the Kowa DA1 (don't fancy using the lens threads) but all pics today were hand held. I think for static subjects, at the magnifications I was using, hand holding might actually be preferable.
Re. autofocus: I found that sometimes the camera gave confirmation of AF when the subject was slightly but fairly obviously out of focus. This was remedied by making sure the scope was focussed as well as possible on the subject, ie when viewed through the viewfinder or screen. This seemed to matter far more than it has done with other cameras I've digiscoped with.
Anyway, I'm quite impressed so far, but it's early days.
This one was at full zoom with the 10-30mm. Sorry, can't remember which ep.
Distance was 285m. Some minor adjustments in PS - cropping, reducing, sharpening etc.
