With almost 600 years of existence, telescopes have become an important component of modern research. Click here to learn What Do People Use an Icom Radio for?

They allow everyone – from regular people, employees, amateur astronomers, to scientists and experts – to readily use their amazing optic capabilities and make distant objects appear closer.

The telescope made its debut in the Netherlands. In October 1608, the national government in The Hague deliberated on a patent application for a gadget that assisted in “viewing remote things as if they were nearby”.

He made it out of a convex and concave lens housed in a tube. Objects were enlarged three or four times as a result of the combination. Check out What Do People Use a Kenwood Radio for?

Galileo solved the problem of building a telescope the first night after returning to Padua from Venice and built his first telescope the next day.

He used a convex objective lens on one end of a leaden tube and a concave eyepiece lens on the other, which became the foundation for today’s telescopes.

Today, a telescope is an instrument used by astronomers to observe distant things. Most telescopes, particularly big ones, collect and concentrate light from the night sky using curved mirrors.

The original telescopes focused light by employing lenses, which were curved pieces of transparent glass. Learn How Good Is The Baofeng Radio Range? And What Do People Use a Baofeng Radio for?

What Can You See?

The 100mm is an excellent entry-level reflector telescope with parabolic main mirror optics, which means no plastic lenses like those seen in some other beginner telescopes.

Many astronomers can view the beautiful features of the night sky with a 100mm telescope. Several craters will be visible on the Moon, and features of Jupiter and other planets will be visible from bright metropolitan locations.

Even from gloomy locations, a good view of the Milky Way and other deep-sky objects is possible. It provides a clear view of different celestial bodies, including galaxies.

A 100mm telescope may reveal characteristics of planets such as Jupiter, Mars, Neptune, and Saturn and its rings. Check out What Do People Use a Yaesu Radio for?

When you observe the planets in an area that is urban and polluted with light from street lamps, homes, cars, etc. a 100mm telescope paired with an eyepiece will provide you with a good image of the planets.

Pluto is just beyond the limit of magnitude that these telescopes can reach. You’d need perfect conditions to view it, and even then, it’d be difficult to spot since it might be mistaken for a star.

It will be out of reach 99.99 percent of the time. All of the other Dwarf Planets are also hidden from view. Click the link to find out: Should You Disconnect a Coax During Lightening Storm?

You should be able to see any star with a limiting magnitude less than 13.6. This covers all the constellations and hundreds of stars that are not visible to the human eye.

Features of 100MM Telescope

When a telescope is referred to as a 100mm telescope, it has an aperture of that size in millimeters. In a telescope, the aperture is the size or diameter of the larger frontal lens.

This is the lens in your telescope that collects light. More light typically equals a crisper, clearer image; thus, a larger aperture is nearly always preferable, but it also comes at a greater price.

Because astronomers prefer to utilize the metric system, apertures are commonly stated in millimeters. In the instance of 100mm, this equates to around 3.9 inches.

It’s a tabletop telescope large enough to discover and view things in the night sky while remaining compact enough to easily be stored anywhere or kept on a shelf or desk.

When looking from reasonably dark skies, it’s the ideal telescope for a wide-angled, view of the galaxy and other deep sky objects. Learn the Optimal Height for 40m Half Square

A 70mm or 80mm telescope cannot provide the level of detail that a 100mm telescope can. They come with effective and strong eyepieces that improve the vision and give more magnification.

As a result, always use a telescope with an efficient eyepiece that helps you to see planets more clearly.

The tiny telescope will astound you and your family with stunning, detailed views of the night sky thanks to its large, 100mm aperture parabolic main mirror and 400mm focal length.

You may examine the Moon’s cratered surface in-depth with this powerful reflector, investigating highland summits and enormous, flat lunar “seas” of dark stuff.

Bright planets such as Jupiter, Saturn, and Mars glow brightly even when viewed from metropolitan areas with poor visibility.

The telescope can gather enough light to detect open and globular star clusters, dazzling hazy nebulas, and even a few distant galaxies on extremely clear evenings when observing from places with dark skies.
