When should I use my binoculars on a tripod?

Binoculars are a great optic simply because they are extremely portable and need no other accessories. However, if your binos have large objective lenses, are high-power, heavy, or difficult to comfortably hold for any length of time, you’ll need to use a tripod to steady your view. Generally, binoculars that have a power higher than 10x and/or an objective lens larger than 50 mm usually require a tripod for satisfactory viewing.
