6 Great Binoculars under $300 for Stargazing in 2023

Don’t get me wrong: stargazing with our eyes is great. Nothing has the same effect on our mental state as starlight entering our eyes after billions of miles of light-speed travel across the galaxy. But there is something special about unlocking a deeper level of the night sky with equipment like binoculars or a telescope.

That’s why I’ve been working on a series about the best telescopes and binoculars for every budget, and in this post I’ll be highlighting the best binoculars under $300. (You can see the rest of the series here.)

But aren’t there more than just six great astronomy binoculars under $300, you ask? You’re right – there are. I also have lists of the best astronomy binoculars under $100 and under $200. Together this gives you lots of options to find the right pair of binoculars for you under the $300 mark.

If you’re not familiar with how binoculars work, there are two numbers provided for each product. The first is the magnification offered by the binoculars; the second refers to the size of the objective lens in millimeters. So for 7×50 binoculars – for example – they offer 7x magnification, and the objective lens is 50mm in diameter. The larger the objective lens, the more light is let into the lens – creating brighter and potentially clearer views. However, larger lenses weigh more which can be uncomfortable when stargazing – that’s something to keep in mind as you choose a pair of astronomy binoculars under $100 from this list.

Note: Lens and binocular prices have been very volatile in the past two years due to supply chain issues. Note that prices might vary widely from the prices I reported when this post was last updated.
