Best Telescope For Teenager

With so many models with so many features available today, it can be a tedious task to find the best telescope for a teenager.  We have analyzed the main features ( aperture, focal length, ratio, portability, affordability etc.) that make a good telescope for intermediates that you can use to enjoy the night sky and fulfill your love for astronomy.

Best Reflector Telescope 

Celestron – AstroMaster 130EQ

The telescope is fitted with a 1.25 rack-and-pinion focuser and two eyepieces to get new users started – a 10mm that yields 65x power and a 20mm for a 32.5x magnification. 

The 20mm eyepiece integrates an erecting system to correct images horizontally and vertically to allow easy terrestrial use. 

The AstroMaster 130EQ also features an unmagnified red-dot finder to help set-up, align and navigate easier.

Celestron’s AstroMaster 130EQ 130mm f/5 Reflector Telescope features a 650mm focal length and an oversized parabolic mirror that produce detailed images of the Moon, clear views of the planets, and the ability to resolve distant objects such as nebulae and galaxies.

The 130EQ comes on a lightweight German equatorial mount that works well enough for the 130 mm f/5 OTA, and it should work okay with a DSLR camera piggybacked on top.

Since it can get quite hard to keep the object in the view because of the Earth’s rotation, there is an upgrade for this mount to help you with that. 

It is a simple clock motor which you turn on after you get the object in the view and it will track the object keeping it in the middle of the eyepiece. It’s much easier to stargaze like this rather than twisting the knobs while looking through the eyepiece. The motor is not included but it can be bought separately.

The Celestron’s AstroMaster 130EQ is one of the best budget telescopes for teenagers as not only is it great for planetary viewing, with the moons of Jupiter and rings of Saturn being star attractions, but being a reflector telescope with a wide aperture, it could be one of the cheapest telescopes on offer that can decently display deep space objects.

At just 17 lbs total weight and thanks to its compact design, the Celestron AstroMaster 130 EQ is very portable. You can take it literally everywhere with you, unlike heavier and bulkier telescopes for professional use.

Best Compact Telescope 

Celestron – PowerSeeker 127EQ 

The Celestron PowerSeeker 127EQ telescope is a Newtonian reflector, which means it uses mirrors to gather the light of the skies, and reflects it for viewing. With mirrors being much less expensive to produce than glass lenses, reflector telescopes offer more value in terms of inches of aperture.

The PowerSeeker 127EQ comes with two eyepieces (4mm and 20mm) and a 3x Barlow lens.

The 5-inch mirror on the 127mm PowerSeeker model limits useful magnification to about 250x, which is achieved using the 4mm eyepiece.

The larger 20mm eyepiece provides a more useful 50x magnification. This grows to 150x when coupled with the 3x Barlow.

If you’re considering an additional eyepiece, something like a 15mm Plossi would be a good option. This provides you with 66x magnification, or 198 when coupled with the Barlow. 

The telescope is ideal for near and deep-sky observation, Celestron’s PowerSeeker 127EQ 127mm f/8 Reflector Telescope features a respectable focal length and a large, parabolic mirror that produce detailed images of the Moon, clear views of the planets, and the ability to resolve bright distant objects such as nebulae and galaxies. 

The beauty of a Newtonian telescope is the longer focal lengths which can be offered in much shorter tube sizes—1000mm focal length in a tube which is only 20 inches (508mm) long . 

best telescope for teenager

The PowerSeeker 127EQ is highly portable and one of the best telescopes for teenagers or amateurs. You could easily fit this telescope and tripod in the trunk of a car and still have room for your other equipment, or maybe a late night picnic.

Best Telescope For Teenager Buying Guide

Buying a telescope for home use is an important step towards a new level of appreciation for the night sky, and the wonders found within it.

best telescope for teenager

Wondering what features you should look for in a telescope for teenagers? It helps when you know precisely what to look for in a telescope before you spend a fortune buying it. Many people feel frustrated if the brand they purchased couldn’t fulfill its purpose, this can be daunting especially if you are a teenage beginner. What telescope should you buy? You can use the following explanation as a guide to enable you to choose the right telescope.

Features To Consider When Choosing A Good Telescope For Teenager

Types of Telescopes

It’s crucial to look at the kind of telescope you want to buy. There are three main types, reflector, catadioptric, and refractor.

The reflector makes use of mirrors while catadioptric uses mirrors and lenses, and refractor utilize lenses as their optical material.

Reflector telescopes – The reflector uses glossy surfaced mirrors to gather light, after which it then cast a reflection of the image. The light collected at the rear mirror is transmitted into the eyepiece.

Refractor telescopes – The refractors utilize various lenses to gather the light which it then reflected to the eyepiece. Refractors are able to transmit 90% of the light rallied in them. They are long-lasting and easy to maintain.

Catadioptric – Catadioptrics transmit 64 to 75% of the light it has collected. It combines all features of reflectors and refractors, and this is because it uses both lenses and mirrors to gather light.


The aperture size is also one of the features you should consider when choosing a telescope. Aperture size is the diameter of the mirror or lens which gathers the light. The size of the aperture determines how bright and sharp the image will be.

Taking into account, a refractor telescope should have a 6-inch (150 mm) mirror at least while a reflector requires a 4-inch lens.

Focal Ratio

Another feature you should consider is the focal ratio. It is known as the speed of the optics. This characteristic depends on the focal length. You should look out for this crucial feature, usually the longer, the better. Use the following as a guide for focal ratio range.

Focal Length

Focal length is the measurement in millimeters from the objective to the eyepiece and it determines the magnification of an object when you pair your telescope with an eyepiece. This is why eyepieces are listed with millimeter measurements the same way focal lengths are listed with millimeter measurements.

The distance is typically the measurement from the lens to the eyepiece and represents a theoretical distance based on how light bounces and a picture is perceived by your eye or a camera.


The performance and efficiency of a computerized telescope are determined by its magnification. The magnification capabilities of a telescope are intertwined with the size of its aperture. So, a telescope with a large aperture allows for higher magnification.

Using a telescope with a higher magnification, you will be able to see distant objects clearly. Keep in mind that the diameter of the eyepiece of a telescope can also affect magnification.


When talking of eyepieces, the focal length should be taken into account as well. Focal length and eyepieces work hand in hand.

One thing most people don’t know is; the higher the eyepiece size, the lower the magnification is and vice versa. Usually, manufacturers include two or three eyepieces of focal length between 5mm – 35 mm range.


Since stargazing and celestial adventures take place outdoors, you will need a telescope that you as a teenager can easily move outside and store away afterwards.

Most of the telescopes are light and compact. It is the mounts, steel tripods, counter weights and additional accessories that make the entire set bulky.
