What is the best way of focusing my Digicam for use with a telescope?
Accurate focusing is the most critical stage of astronomical imaging and it’s importance cannot be over-stressed. It is difficult to judge correct focus using the small built-in display so either use an external monitor (a small TV or PC display helps) or another focusing aid such as a Hartmann or hole-mask. Use maximum digital zoom whilst focusing so that errors are more easily seen, then back off the zoom to frame the object normally.
