What magnification of binoculars is better for stargazing?

  • 10×50 Binoculars – handholding is still possible, the optic is still portable, and the 10x magnification gets you a bit closer to the star – the 10×50 binocular is also a popular choice for viewing the night sky.

What are 10×50 binoculars good for?

What are 10×50 binoculars good for?

  • In the case of 10×50 binoculars, the magnification is 10x. This means that objects will appear 10 times closer when viewed through these binoculars. This is a powerful enough enhancement for viewing distant scenery, wildlife, and sporting events.

Cons

    10×50 binoculars can be heavy, which may make them unsuitable for birdwatching.
  • Narrow field of view
    Higher magnification binoculars can have a narrow field of view.
  • Eye relief
    Some 10×50 binoculars have limited eye relief, which can make it difficult to see everything in the field of view, especially if you wear glasses.

For me – 15×70 Binoculars

  • I have tried several different types of binoculars for stargazing and almost without fail when I want to look through binoculars for stargazing I would go straight for my 15×70s.

  • It will be about the largest you can handhold without everything dancing around too much in your view.
    O
  • The weight is manageable allowing you to hold and view objects for some time before your arms start to get too tired. (10x magnification is a lighter than 15x magnification binoculars.)
    O
  • They are not too big so remain easily portable.
    O
  • Cost-effective.

  • A generous field of view, they will give you some gorgeous views of open clusters, the brighter nebulae, the Moon and even the planets.

  • The 50mm or 70mm diameter objective lenses will help you see much fainter stars and objects than the naked eye.
    O
  • Good contrast, the low 10x or med 15x magnification ensures objects remain bright – in 20x binoculars, the same amount of light will be spread over a larger part of your view making the same image dimmer with lower contrast.
    O
  • No squinting and good eye relief.
    O
  • A 5mm exit pupil fits nicely into a dark-adapted human pupil providing comfortable viewing, even for spectacle wearers.
    O
  • 10x50s Binoculars provide an upright non-inverted image, so you can hop between stars and constellations with ease.

I think I would to say 15x70s spec that makes them the go-to for most astronomers, but 10x50s will perform better for binocular astronomy than the 20x100s, sure you could mount them on a tripod to stabilise things, but for me, that takes away the beauty of using binoculars to view the night sky.
