Picking an entry-level telescope is often much harder than picking a high-end one. This is because there are loads of low-quality, shoddy scopes that you have to sift through. Low-quality telescopes have given a pretty bad name to the astronomy industry. They make people think that inexpensive telescopes aren’t worth buying at all. However, the reality is that there are plenty of good telescopes out there that are affordable. You just need to know what to look for. Today, we’re going to talk about the best telescope under 100 dollars. We’ll start by discussing a few key factors that you need to be aware of. Once you know how to identify these factors, you’ll be able to identify good telescopes quite easily.


How to Spot a Good Telescope

A size of a telescope’s price tag doesn’t always determine its quality. What you need to look for are the components that make up a telescope. This is a lot easier than you might think. A telescope is made of numerous parts, but you only need to care about a few important ones. Especially if you’re someone who’s new to astronomy and don’t want to get into confusing things. We’ve talked about all the major components of a telescope in great detail before. You can read about them over here if you’re interested in the nitty-gritty details. If you want the TL;DR version of things then you can continue down below:

  • You should focus on the aperture (lens diameter) of a telescope.
  • You should also keep its focal length and focal ratio in mind.
  • Lastly, you should keep a telescope’s magnification in mind.

These are all the major things that you need to be aware of. Now before we begin reviewing telescopes, here’s a word of caution. At a 100 dollar price range, there’s a pretty good chance that you’ll come across toy telescopes. These aren’t telescopes at all, and you should steer clear of them. The telescopes that we’re going to talk about are definitely not toys. They’re made by reputable manufacturers and are proper astronomical instruments.
