Are you interested in buying a telescope for yourself or your child? Taking up astronomy as a hobby doesn’t have to be expensive.
There are many entry-level telescopes available that will not break the bank. Although they might not be as powerful as the ones used in science labs, they can still enable you to be awed by the scope of the universe and the mysteries of the galaxy.
Following are the top 10 telescopes available on Amazon for under $400 for children, students, and adults.
What To Look For In a Telescope
If you want to take up amateur astronomy, it is important to know what kind of telescope to get. In this section, we’ll look at different kinds of telescopes and what to look for when buying one.
Refractor Vs Reflector
Most telescopes that you will find online will fall into either the refractor or reflector category.
A refractor telescope uses two lenses. The larger one is at the end of the viewing piece, while a smaller lens is located on the side where you gaze into.
They are usually long and slim and are a good choice if you want to view large, bright objects such as the moon, planets, and stars.
A reflector telescope uses a mirror at the end of the tube to gather light.
These telescopes are usually shorter and wider and are ideal for wide-field viewing and for gazing at deep-sky objects, such as nebulae and galaxies.
Refractor telescopes are usually more expensive than reflectors for any given aperture size.
The third type of telescope you may see is the compound or catadioptric telescope. This type of telescope uses both lenses and mirrors and comes in many different designs.
In the listings below, you will notice that each telescope has an aperture size. The diameter of the aperture (the lens or mirror that gathers light) is important.
The larger the aperture, the more finer details you will be able to see. Telescopes with larger apertures are also better for seeing faint objects.
Focal Length and Focal Ratio
The focal length is measured from where the light starts to gather (either in a mirror or lens) until where it converges to focus. The focal ratio (f/x) is achieved by dividing the focal length by the aperture size.
The higher the focal ratio, the more magnification power the telescope will have.
Keep in mind that a higher magnification power is not always better. For example, you might be able to see an object magnified closer, but it might be fainter and less bright.
A lot depends on the light-gathering capabilities of the telescope as well.
Many telescopes will come with a set of different eyepieces, each of a different size. By swapping the eyepieces, you can change the focal ratio or magnification power.
For example, if the focal length of the telescope is 250mm and you use a 25mm eyepiece, the magnification power will be 10x. If you use a 10mm eyepiece, the magnification power will be 25x.
Swap your eyepieces based on what you want to look at and how much detail you want to see.
For example, lower magnification power can be useful for viewing dimmer objects. It can also make it easier to find objects and keep them in your focus.
It’s important to make sure that your telescope comes with a good mount. While you may be able to use an existing tripod with your scope, it may not be the best option for viewing and tracking objects.
Some telescopes come with a tripod, while others are meant to be mounted on a table. In any case, there are two main kinds of mounts: Equatorial and altitude-azimuth.
Equatorial mounts must be aligned with the North Star, Polaris. Once you do that, you can easily use it to track objects as they move across the sky.
A single axis can be used to track planets, shooting stars, and other phenomena. Some equatorial mounts are motorized.
An altitude-azimuth mount will allow you to easily move the telescope up, down, left, and right. They are usually lighter than equatorial mounts.
The weight of the telescope is another thing you should consider. If you are looking for a lightweight telescope to take wherever you go, you might have to forego some other qualities and opt for a less powerful scope.
Your telescope might come with guides and other resources. For example, many of the telescopes below include a free download of the Starry Night software.
This software allows you to do things such as:
- Display a realistic night sky from any location on earth
- Display any date and time in the past or future
- Create observing plans
- Display current imagery from satellites
- Control “Go To” motorized telescopes through a serial interface cable
Ten Best Telescopes for Under $400
Following are the best affordable telescopes on Amazon for those with a budget of up to $400.
The Moonee Suncore telescope is a basic telescope with limited power. However, for its price, it provides great value.
You can give your kids a chance to explore the moon and its craters, as well as other phenomena in the sky.
The refractor telescope has a 70mm aperture lens. It comes with two eyepieces, which are interchangeable.
The 18x eyepiece offers you a wide view while the 90x eyepiece offers you a narrower range but a closer view.
Your purchase includes a free tripod. Setting up your telescope is easy and only takes a few minutes.
If you are interested in studying astronomy yourself, you might be better off investing in a higher-quality telescope. However, if you want to get something your kids can enjoy and which can help them with what they are learning in school, this is a good choice.
The Aomekie beginner telescope features fully-coated glass optical elements for clearer vision. This refractor telescope has a 70mm aperture and a 300mm focal length.
It comes with two interchangeable eyepieces. The 6mm eyepiece will give you a 15x magnification power and the 20mm eyepiece will give you a 50x magnification power.

By using the Barlow lens with the 20mm eyepiece, for example, you can achieve a magnification power of 150x.
The erecting eyepiece not only increases magnification by 1.5x, but it also makes it easier for kids to focus on what they are seeing. Usually, images on such a telescope will appear in an inverted manner, but the erecting eyepiece changes this.
This telescope comes with an easy-to-setup tripod. It has aiming control and a lock handle to help you focus on what you want to see.
