Are 10×50 Binoculars Good For Astronomy?

10×50 binoculars can be used for astronomy, but they are not ideally suited for this purpose due to two reasons:

The 10x magnification is right at the maximum for using binoculars by hand. Ideally, you want smaller than this if you scanning the sky by hand for things like meteor showers, or you want larger for more detailed views of planets and other objects.

The 50mm aperture is slightly too small to provide you with meaningfully good views of night sky objects. I generally recommend 70mm as the minimum for binoculars or telescopes for astronomy.

Therefore you can go in two different directions for binoculars for astronomy:

Low magnification for night sky observing by hand. Something like a pair of 7×50 binoculars will actually be better for this than 10×50.

High magnification and high aperture for detailed observation of specific objects. For example, the 20×80 Binoculars.

10×50 binoculars can certainly be used for casual astronomy and if you already have a pair for other purposes you can definitely have a go at using them for stargazing. However, they would not be our recommended option if buying specifically for this purpose.
