Digiscoping is the making of photos and videos with a digital camera or smartphone through a Spotting Scope, Binoculars or Telescope. In this way it is possible to enlarge the object even more, achieving amazing results. The most beautiful results are achieved when using a tripod, so that all movements are kept to a minimum.
