The 7 Best Binoculars Under $100 for Stargazing

When you first get started stargazing, you might have a lot of questions. What am I seeing? Is that a planet or a star? Will a telescope or binoculars help me see even more? Plus loads of others too! But as someone who’s new to astronomy, you might not want to shell out a ton right away – after all, some binoculars and telescopes cost upwards of $1000! But don’t worry – they don’t all cost that much; here are the best binoculars under $100.

If you’re budget-conscious and/or brand new to stargazing and just want to get started without spending a lot, this post is for you. There are some decent options when it comes to astronomy binoculars under $100, though you need to pay attention to the brand, objective lens, and magnification to ensure you buy something that’s powerful and well-built.

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.

Now that you have the basics down, take a look at my list of the best binoculars under $100 for stargazing. You can certainly find one to start unlocking greater mysteries of the night sky without breaking the bank.
