Following on from Kevin's remark, here's a single frame of 40secs taken
with my 8"SW f/5 Newt on HEQ5, unguided, Canon 1100D. Try that with an 80mm refractor.
It's not a quality image, but it shows what you can get with just a single shortish exposure with an 8" scope.
Best viewed at about 75% screen.
