Telescope Under $100 Buyer’s Guide

Before you actually go out and buy a telescope that costs less than $100, it is a good idea to consider a few things that you should look for before making your final purchase decision. Generally, telescopes under $100 do not have loads of features and do not have the bells and whistles that expensive, high-end models have.

Nevertheless, the best telescopes under $100 are good and solid scopes that are good for observing terrestrial and celestial objects that are closer, which do not require large aperture telescopes. The best telescopes under $100 have the capability of seeing deep-sky bodies that are brighter such as Messier objects. Most of the good models feature simple altazimuth mounts and you can expect solid tabletop or tripod mounts that will do your job effectively while ensuring that they do not burn a hole in your pocket.

The best telescopes under $100 are compact and highly portable, offering good performance, irrespective of wherever you take and use them. Also, these scopes are very easy to set up and use, even by beginner astronomers. Now, let’s take a closer look at some important things that you should consider when buying the best telescopes under $100.


This is a very important consideration while selecting the best telescope under $100 and one where you need to be cautious. Low-quality optics can compromise the performance of the scope; however, high-quality optics can be quite expensive. A major problem with low-quality optics is poor image clarity and chromatic aberration due to inefficient transmission. However, the telescopes under $100 that we have included in our list of best telescopes under $100 feature high-quality optics at very affordable prices.


Typically, the best telescopes under $100 have larger apertures, which firstly allow more light and expand the viewing capacity of the scope. Usually, objects that are at a greater distance are more difficult to see because they transmit very little light to your eye; however, with a larger aperture, you can see more objects in the night sky in more detail.

Secondly, the aperture of the scope is directly proportional to its f-ratio, which is the ratio of the tube length to the aperture. The f-ratio can affect the focus and clarity. If the f-ratio is very small, the images will not be sharp and crisp.

And, finally, the aperture size is equal to the field of view. Using a telescope under $100 with a very small aperture at high levels of magnification results in poor-quality images and unpleasant viewing experience. As the aperture size increases, the items that can fit into the field of view also increases and your viewing experience also becomes more pleasant.


Usually, telescopes under $100 do not have impressive mounts. So, it is important to look for scopes with a simple, yet stable mount that will let you view without image vibration. Telescopes having smaller mounts are easier to use and are more stable.


While accessories can help to increase the functionality and flexibility of the telescope, the accessories included with the telescope should not be instead of poor optical quality.

In conclusion, the best telescope under $100 will offer all you need to view terrestrial objects, as well as for stargazing. It is always a good idea to look for a telescope that offers the best optics and then see if you get any extra bells and whistles at the under $100 budget. So, what are you waiting for? Grab your favorite best telescope under $100 and start your stargazing journey.
