What can you anticipate from 50mm telescopes?

50mm telescopes are low-cost, entry-level instruments. They are designed and promoted for first-time customers and parents wishing to purchase their children’s first telescope.

The “50mm” in the name stands for “50 millimeters,” relating to the diameter of the telescope’s front lens, also known as the aperture. Fifty millimeters is approximately 2 inches.

Telescopes’ dimensions and specifications are often in metric measurement units (millimeters, centimeters, etc.). Read All You Need to Know: Peripatetic Morse

Because these telescopes have a 50mm aperture, you would be able to see things with magnitudes (luminance) less than 12. This means it is possible to view many stars that aren’t visible to the naked eye and many of the celestial bodies.

The Moon will appear fantastic through a 50mm telescope, and you’ll be able to view all of the main features and natural formations.

Mars, Jupiter, and Saturn will be observable for as long as their rotations permit. You may be able to see some detail on Mars, but the remainder will be shown in a single hue.

Venus will be seen as long as it is viewable in the sky (sunset, sunrise). Find out Will Placing a Radio Tower on Your Property Enhance Your Antennas?

Under some scenarios, Neptune and Uranus may be seen, although they are difficult to identify because they resemble planets with slightly different colors.

The asteroid belt, meteor storms, and other transient displays can be viewed.

A limited amount of deep, celestial objects, notably most Messier shapes, can be observed; nevertheless, smog will play a significant role in whether or not you can see them. If you reside in a major city, you might not be able to tell them apart as well as in a rural location with little light pollution.

As you can see, 50mm telescopes are rather limited in terms of the types of objects that may be observed and the clarity of the picture produced by the lens. Nonetheless, they might be a good entry-level alternative for youngsters and first-time stargazers.

Here are a couple of photographs shot using 50mm telescopes to see the effects for yourself. If you need to use them for astrophotography, you can easily locate a phone adapter to go along with them, and some contemporary versions even come with one in the package.

Using a DSLR with all these telescopes is also feasible, albeit this may be overkill. If that is the case, a telescope with a larger aperture might be preferable. Click here for Tropospheric Ducting: Everything You Need To Know

Is it worthwhile to invest in a 50mm telescope?

We’ve worked with many telescopes, ranging from simple kids’ telescopes to observational telescopes, so here is the deal: 50mm telescopes are by far the most affordable telescopes available.

They are not notably greater than many of the most powerful binoculars available. They are restricted in every aspect, but they have one significant advantage: low pricing.

Here is a summary of the benefits and drawbacks of 50mm telescopes to help consumers make an informed decision:


  • The prices are reasonable
  • Portability: 50mm telescopes are compact and easy to transport
  • Durability: Despite their low price, they are normally manufactured with the same components as more costly telescopes. Thus, the quality remains consistent
  • They are often simple to use and function virtually immediately. Aside from mounting it, very little preparation is necessary


  • Optics are limited
  • You will quickly reach the peak of your learning curve. Those aren’t the types of telescopes that will grow with you
  • Planetary gazing will not provide you with many details
  • They are frequently packaged with low-quality eyepieces

What to Look For When Buying a 50mm Telescope

Here’s a summary of the essential characteristics of a telescope and what they all represent, so you can better grasp how they affect your viewing experience.

There are more parameters, but they are normally determined based on these three. Thus these are the truly important ones.

The diameter of your telescope’s main (frontal) lens is referred to as its apertures. This will determine the intensity of light from the telescope’s tube.

This has always been 50mm (2′′) for the telescopes in this tutorial. When it comes to aperture, larger is better.

The Focal Length

It is the range between the entrance lens and the lens through which the picture is seen. Check out Trans Equatorial Propagation Everything You Need To Know

This is sometimes conflated with the telescope’s “length”; however, this isn’t necessarily true for telescopes having eyepiece exits in the center of the telescope’s frame. A focal length of 600mm to 900mm is appropriate for 50mm telescopes.

Maximum Usable Magnification

This is the greatest magnification supported by the telescope. By utilizing multiple eyepieces with your telescope, you may “switch” among magnifications.

Most telescopes have at minimum two or three alternative eyepieces to provide you with various magnification possibilities.
