Spotting scopes are needed if you want to see detail from an extended distance where binoculars just don't cut it. As magnification is increased it is difficult to hold any optical device steady enough so that the view does not seem to shake. Short of investing in binoculars with built in image stabilization, the next best thing is to simply use a tripod with a spotting scope. Also check out digiscoping gear that will provide the opportunity for an economical means of capturing awesome photographs and images.
