The two 50-millimeter models from Canon are the largest and newest of the bunch. With more manufacturers and models to choose from than ever before, the stabilized-binocular buyer has to make many decisions. It is that first group that is most likely to consider the binoculars reviewed here.

The least-expensive stabilized binocular will set you back as much as a budget midsize telescope. Here is what we found out. A 7x50 or 10x50 binocular has long been considered the best choice for general astronomical observing. It is relatively lightweight, inexpensive, and capable of delivering fine wide-field views of the heavens. However, 10x binoculars only scratch the surface of what can be seen at higher magnification.
