Binocular mounts allow the use of heavier and more powerful binoculars, allowing you to enjoy tremendous wide field views. We recommend binocular mounts be used with any pair of binoculars having more than 10x magnification. The most common and useful type of binocular mount for astronomical observing is the parallelogram type. Parallelogram mounts allow you to raise or lower the glasses without changing the aim point. This is a great feature to have when observing with a group of people of varying height.
