Howie up in Queensland use cameras like the 650D. Collects with EOS Utilities and processes live with astrotoaster (deepskystacker). Gets a pile of live images each session with single 30-60sec shots. No guiding used.
I'd just be concerned that the SCT is slow (@ F10) and will have a small FOV so might be hard without guiding.
