Focal lengths in digiscoping typically range from long (say 800mm) to the ludicrous (5000+ mm) and this brings with it a whole pile of issues. Professional telephoto photographers deal with these issues all the time and digiscoping is no different. It requires the digiscoper to commit time and energy to start to think more like a serious photographer. To understand what shutter speed, aperture, ISO and all those other fantastic things are all about. So, what shutter speed do I need to get a good, sharp digiscoping photo?
