Copernicus,
I would caution you on having high expectations and starting with the complex aproach, unfortunately astrophotography really is one of the things you should start at the bottom and work your way up to make our life easy and efforts rewarding.
I started through the telescope, and ended up with almost exactly what Eric showed, lines instead of stars, for several rolls of film before I switched to piggy-back.
Another alternative if you want to use your telescope optics is planetary imaging with a webcam, and forget about the 350d. Eric might correct me but I suspect it would be possible to do webcam imaging using a barlow on that scope (the barlow allowing you to reach focus). You might even be able to get away with manually tracking (moving the telescope in RA) for the short duration of videos, but it could be frustrating.
Eric, you can fit a t-ring to a 1.25", you just need the right combination of adaptors
The camera ends up a few mm further from the scope in addition to the t-ring.
Good luck, and I'm still happy to help at some ASWA event in the future if you'd like to turn up
Roger.
