The Simmons ProSport 10x50mm Binocular (Clamshell Packaging) is the far end of magnification and objective size for hand held viewing without the wobbles. With that in mind they provide enough power and light gathering ability to double as an astronomical binocular. The moon's craters - especially along the terminator, Jupiter's satellites and the Pleiades resolved into the Seven Sisters make this size optic a very desirable binocular. Terrestrially speaking, back here on Earth, the large 50mm objective increases light transmission in low light twilight conditions when the game comes out of hiding.
A cloudy day need not be an inhibition to good viewing with these multi coated optics when their waterproofing, fogproofing and rubber armoring are calculated into the algorithm. An exceptionally wide 65deg. field of view is an opportunity to scan large areas of panoramic vistas of both the Rocky Mountains and the Milky Way. You'll often be happy that you dropped them in the backpack and won't regret the extra weight.
