Best Monoculars For Stargazing - With Thermal

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.

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.

Thermal monoculars enable the detection of a target in the dark using the radiated heat from the target and its surroundings. Thermal monoculars are better at detecting targets than infrared monoculars, but they are normally more expensive.
