The Best Telescope Under 100 Dollars – A Buyer’s Guide

The Best Telescope Under 100 Dollars

Amateur astronomy is a terrific hobby for kids and adults who love to spend time outdoors or for those who enjoy regular camping expeditions. It is a lot of fun to learn more about the universe and to seek out constellations, stars, and planets with a small lazy campfire crackling on the side.

A quality star gazing instrument is very handy for these types of adventures. In this guide, we will take a look at the best telescopes for under 100 dollars that will give you a much better view of gorgeous celestial objects in the sky.

Comparing Telescopes – The Most Important Features

If you are new to astronomy, it can be difficult to choose the right telescope. They come with a wide range of features, some a lot more advanced than others. The following are some of the most important features to look out for when shopping for a telescope.

Focal Length

The focal length is the distance between the objective lens and the eyepiece. This distance is measured in millimeters. Telescopes with a longer length will give you a smaller field of view but will offer more magnification. For example, a 400mm scope length will give you a much closer view of the moon with less surrounding atmosphere than a scope with a 300mm focal length.

Objective Lens

This is the large lens at the end of the telescope. Larger objective lenses allow more light in but tend to be more expensive. Most telescopes under 100 dollars have an objective lens of 70mm or smaller.


Additional eyepieces are often included with a telescopic kit. These removable pieces come in different sizes and these different sizes offer different levels of magnification. Bigger eyepieces (20 – 25mm) offer lower magnification, while smaller ones (6-10mm) offer more.

Barlow Lens

It is good to look for a telescope that has a Barlow lens. It is fitted with your eyepieces and will double or triple their magnification (2x lenses for double, 3x lenses for triple). This can greatly enhance your close-up view of planets or the moon with your standard eyepiece.

The James Webb Space Telescope is currently the strongest telescope in existence. This was created in 2010 and cost around 1 billion dollars. This massive creation can view further than ever before and is positioned in space one million miles above sea level.

While the small telescopes we compare on this list aren’t nearly as effective as the Webb or the Hubble, they still offer remarkable magnification for their portable size and are perfect for getting started in astronomy.

Here is a quick look at the 5 best telescopes to get for your stargazing adventures.
