Of course, the S/N ratio is much better to start with. There is some loss using the many shots idea though. Other calculations and my own experience suggests the 100 x 1min shots would be the equivalent of about 70-80 min of longer exposures.

Hi H0ughy and Itchy,
Just another tid-bit as well, ISO-200 on the Canon 300D without doubt gives me the best signal/noise ratio compared to other ISO settings. Oh and Parameter Set 2 on the camera uses less in-camera processing (DGIC or whatever they call it) of the image than does the default setting of Param. Set 1.
