I use DSLRFocus with my 350D, coupled with a 10-1 micro focuser and have found that I achieve focus very quickly. I first manually focus on a bright star near where I am going to shoot, then, using DSLRFocus tweak the focus until I am satified with the result, then use the software to control the shoot. Just be aware when using an SCT that Mirror Flop can be a problem when shooting over the Meridian. I am still learning each time I use the camera, keep at it.
