Portable and Handheld Telescopes: Introduction

Telescopes have undergone significant transformations since the 17th century – or when the first refractor telescope was invented. Note that spectacle-maker Hans Lippershey was credited as the inventor of the telescope and Galileo Galilei as the scientist who pointed the telescope towards the skies. In 1668 Sir Isaac Newton created the so-called Newtonian reflecting telescope that consisted of mirrors instead of lenses. Over the years, improvements in lens technology led to the development of the catadioptric telescopes that employ both lenses and mirrors.

While there’s a wide range of telescopes for both professional and amateur use, portable and handheld scopes are highly popular. In contrast to other telescopic devices for sale, portable and handheld units are light, compact, and easy to use. They can be utilized for a wide range of activities, such as stargazing, camping, bird watching, and hunting.

Talking about size, we should note that giant telescopes are the most sophisticated and powerful units that enhance the scientific study of distant objects, such as nebulas, novae, and asteroids, by their emission or reflection of electromagnetic radiation. Note that the first giant reflector telescope was built in 1789 by William Herschel. The design of large and computerized units (including radio, infrared, and gamma-ray telescopes) has evolved during the 20th century – the fast-moving century when space agencies also started launching telescopic devices into space.

Portable and Handheld Telescopes: A Buyer’s Guide

Portable and handheld telescopes are highly popular because of their light and compact designs. While there’s a wide range of units and competitors on the market, there are three main factors users should consider before purchasing a telescopic device:

  • Requirements
  • Specifications
  • Total cost

Requirements: When choosing a telescope, users should decide what objects they want to see (e.g., deep-sky objects) and where they’ll be viewing them (e.g., rural areas). As stated above, there are three types of telescopes: 1) refracting telescopes that employ lenses; 2) reflecting telescopes that use mirrors; 3) catadioptric telescopes that utilize both mirrors and lenses. Note that they all can be portable (when clearly stated).

When it comes to portable telescopes, two of the most important aspects to consider are size and weight. Smaller items are easier to operate, especially units with longer focal lengths. Weight, on the other hand, can vary according to the materials used, with aluminum being light and sturdy material at the same time. If prospective buyers are planning on using a tripod, they should consider its weight as well.

Specifications: Aperture and magnification are the two main specifications that should determine purchasing choices. Higher aperture translates into high levels of light-gathering, which is ideal for observing deep-sky objects.

Magnification is another vital characteristic to consider. Usually, the maximum useful magnification should be 50 times the unit’s aperture in inches or twice of its aperture in millimeters. Note that excess magnification can lead to blurry images.

Total costs: Telescopes come in all shapes and sizes, with aperture, optical quality, and materials used being among the most crucial factors that determine costs. When it comes to portable and handheld units, the materials used are essential. To provide an example, sturdy material, and waterproof exterior coating are mandatory to ensure a long lifetime and user comfort. We should note that some small units can be priced as high as stationary telescopes.

Accessories, such as stands, mounts, and camera adapters, can increase the final cost of a unit. Note that there are two types of mounts: equatorial and altazimuth, with altazimuth mounts being popular among amateur astronomers. The carrying case is also essential for portable models; while hard cases are good for traveling, soft or backpack styled cases are ideal for hiking.
