The Good
The Bad



Trying to find the best inexpensive telescope among the myriad of options out there can a seemingly never-ending task as the time that it can require out of you can end up making you feel discouraged. We believe that we can help simplify your decision-making process by giving you the information you need in the buying guide below. By taking into account the information we provide, it will be much easier for you to narrow down your searches to just one option.


The Aperture, a crucial component

If you’ve spent some time browsing through all the various options that the market has to offer, you’ve probably noticed one key feature that keeps getting mentioned, the aperture. The aperture of a telescope is the most important thing you have to consider when making a purchase because it can make the difference between a good and a bad product.

So what is the aperture? The aperture is the opening through which the light enters. It’s measured in millimeters or inches, and it measures the diameter of the lens or mirror inside the scope. Because in order to view things properly we need light, if you want to be able to see deep space objects well, you need a large aperture.

In the case of the aperture, size does matter, and bigger is always better. The larger the diameter, the more light will be able to reach your eye, and with more light, you will be able to view the details of the object you’re looking at better. When considering buying a good telescope for the money, you should consider the aperture as the deciding factor.


The focal length

The aperture is the most important part of your telescope, but the focal length comes in a close second. Just as with the aperture, a bigger focal length is always better and recommended. The larger it is, the better will it lend itself to high-magnification viewing without making the image get fuzzy.

While the aperture is the most important factor when it comes to deciding on the product you want to buy, the focus can make it easier for you to choose between two or more devices. If they all have the same aperture, the one with the larger focus could be the ideal choice for you.

Of course, you have to keep in mind that the size of the focal length will inevitably influence the size of the device. The bigger the focal length, the larger and longer your product will be. If size is a major factor for you and you want a more portable device, pay attention to this detail.



The magnification of your telescope is a crucial aspect, but without proper lenses, you can have the most advanced eyepiece money can buy and it wouldn’t make much of a difference. The aperture and the focal length have an important part in deciding what magnification is best for your device.

The rule of thumb is that you can get anywhere between 20x to 50x of useful magnification per inch of aperture. This makes it easier for you to get the full benefit out of even the most affordable products on the market when considering that a magnification of 50x is enough to view Jupiter and its moons.

It is important to note that the magnification is given by the eyepiece which can be easily replaced. If you are not pleased with the magnification of the eyepiece that your product comes equipped with, it will be easy for you to swap it with another, if your lenses permit.
