What magnification of binoculars is better for stargazing?

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

• Heavy
  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.

50mm or 70mm diameter

50mm or 70mm diameter

oooo

• 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

• 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.
