Best Waterproof Monoculars For Stargazing

The main consideration when selecting a monocular are the magnification level and objective lens diameter, which determine the optical capabilities of the monocular. The bigger the objective lens diameters, the better the image quality and the heavier the monocular may get. Waterproofing and night vision (thermal or infrared) are also important factors to consider when selecting a monocular.

Waterproof monoculars prevent moisture and dust from entering into the monocular and ruining it during outdoor activities. It is hermetically sealed and normally has anti-fog nitrogen/argon gas inside. If you plan on using your monocular on open water, choose the marine type.

Monoculars for stargazing require magnification of at least 10x and at least an objective lens diameter of at least 42mm to make sure enough light is captured, but it can be too heavy for hand operation. A good 10x42 monocular weighs about 1.5 lbs. (0.7 kg), which may require a tripod for stabilization.
