Why Choose a Celestron Telescope?

Celestron has been a pioneer in producing world-class telescopes since the early 1960s. In the late 1950s, Tom Johnson, founder of Celestron, built a telescope from scratch to introduce his sons to the wonders of stargazing. 

Johnson devised a new manufacturing process to make high-quality telescopes more affordable. 

Before Celestron, Schmidt-Cassegrain telescopes (SCTs) were produced individually by master optical craftsmen who spent hours hand-figuring the glass. 

He streamlined this process by developing ultra-precise match plates, which allowed for mass production of the Schmidt corrector. 

This technique allowed Johnson to create telescopes of unparalleled quality and bring them to market at a surprisingly low price.

Today, Celestron is known for creating quality optics that last. When you buy a Celestron telescope, you’re getting solid materials, clear optics, and an innovative design with plenty of capabilities.

10. All-Star Polar Alignment

The All-Star Polar Alignment technology lets you precisely track the motion of the sky. This ground-breaking technology present in the best Celestron telescopes allows users to choose any bright star while the software calculates and assists with polar alignment.

12. Fastar Technology

The Fastar technology increases the speed of the optical tube, a whopping 28 times. It basically increases the speed and sensitivity of Celestron optical tubes, allowing for brighter and more detailed images with shorter exposure

Features To Consider When Choosing A Celestron Telescope

Even with an excellent brand such as Celestron, you need to understand what the telescope’s specifications mean and how they affect performance. 

Here are some important factors to keep in mind as you choose your best Celestron telescope.

1. Aperture

The most important aspect of any telescope is its aperture, the diameter of its main optical component, which can be either a lens or a mirror.

A scope’s aperture determines both its light-gathering ability (how bright the image appears) and its resolving power (how sharp the image appears).

Celestron’s aperture sizes range from three to 11 inches in diameter. When learning how to choose a telescope, knowing all you can about the aperture is crucial to your ability to see the night sky.

2. 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.

The focal lengths of Celestron telescopes range from 360 to 1,250 millimeters.

3. Magnification

The larger the aperture size, the higher the magnification of the telescope. Most Celestron telescopes have between 120x and 480x magnification. The higher the magnification, the easier it is to view faraway objects.

4. Eyepieces

Eyepieces determine the magnification and field of view of a telescope. Different eyepieces are used to view different objects.

While most Celestron telescopes have only one eyepiece, certain models ship with more than one.

Some objects, such as nebulae and star clusters, appear quite large and are best viewed at low magnifications (which give a wider field of view), whereas planets appear very small and are normally viewed with high-magnification eyepieces.

One of the most common misconceptions in amateur astronomy is that magnification is the most important aspect of a telescope.

In reality, the diameter (aperture) of a telescope determines its power and different eyepieces are used to get the best view of a given object. Often the best view is at a low magnification.

5. Portability features

Size: On average, Celestron telescopes weigh between 10 and 50 pounds. Smaller telescopes mostly include tabletop and travel models. These are lightweight and easy to transport. Larger styles, while much sturdier, are significantly heavier and are best left in the spot they’re most often used.

Tripod: Celestron telescopes are usually made of aluminum or steel. They’re well-built and reinforced to support the weight of the telescope without shifting or wobbling.

Storage: Most travel Celestron telescopes come with travel bags. If you plan on traveling with a larger model, purchase one separately. You may be able to purchase one from the Celestron line or you can use a universal case.
