I have tried with my 500D to image Jupiter through 5X powermate with powermate to camera ring adapter HD at 30fps. Results were disappointing, it would capture in auto ISO only. Jupiter was generally overexposed. I haven't gone through things in detail to see if i can get around auto ISO. Not sure if 30fps is a limiting factor too, I suspect it may be. Modest definition only of Jupiter was achieved with same setup at 1/30 sec i.e. close to 30fps exposure at ISO 400 and 800 still pictures. If anyone else has a great solution I'd be interested.
