Best Affordable Telescope 2023; Reviews

The best affordable telescope is one that has about 3 to 7 inches of the aperture. With the right size of the aperture even inexpensive telescopes can give you an extensive and wide-angle image of the galaxy.

The reflector of your telescope also plays a vital role in obtaining extensive sky images. Most of these best value telescopes come in a two-piece setup with a wide field. A good telescope gives you at least about 20x magnification.

The focal length is also one of the most significant aspects of a telescope that you must take into consideration before buying one.

Features To Consider When Choosing A Good Affordable Telescope

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.

Aperture

Aperture is the first thing you need to evaluate in your telescope. In simple words, the aperture is the diameter of the converging (light gathering) lens of a telescope. In some cases, it is also a mirror.

Aperture is also called the objective. Aperture is generally measured in millimeters or in inches. Generally, well-performing telescopes have an aperture of at least 70mm or more.

The more the length of the aperture, the better you are able to see the details of the objects. However, it also depends on the location from where you’re viewing the objects. For example, from a remote and dark place, an aperture of 80mm can show you very fine details.

You might not be able to see the same details with the same aperture in a city. A telescope’s magnification is also derived from its aperture. For example, most of the telescopes’ magnification is about 50 times more than its aperture.

Focal Ratio

When you divide your telescope’s aperture size by its focal length, you get the focal ratio of the telescope. The focal length is calculated from the main lens or mirror. A telescope with an aperture size of 3.5 inches and a focal length of 35 inches has a focal ratio of f/10.

It is not necessary that a high focal ratio obtains a high-quality image. However, with constant aperture, high focal length can mean it has a longer scope. This also means that the surface area of the telescope has increased.

Focal Length

It is the distance between a telescope’s primary optics and its focal point. It works with the focal length of your eyepiece to produce your desired magnification. In many cases you will get the telescope’s focal ratio instead. This is just the ratio between the focal length of the telescope and its aperture.

Magnification

Any telescope can provide almost an infinite amount of magnifications – this is because you can switch out a telescope’s eyepieces and therefore you always have new options – however two major features will limit your potential to magnify and object further: the telescope’s aperture and atmospheric conditions.

For your given aperture length, the higher you magnify typically the darker your image will be – and therefore harder to see its details.

The best magnification setting is actually 50 times your telescope’s aperture in inches. For instance, a high-quality 4-inch scope at 100mm shouldn’t be pushed beyond 200x magnification, otherwise what you see through it would not be of good quality.

Eyepieces

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.
