The Celestron Explorascope is a compact and versatile Newtonian Reflector, which was built and designed with a beginner in mind.

Compared to other telescopes at this price point and specification, the Explorascope provides great light gathering ability and a lot of flexibility on what and how you observe.

The two eyepieces included providing a range of magnification to benefit from and utilize. Visually it looks fantastic too.

The new and improved Alt-Azimuth mount was only recently released and comes with the added stability of the optical assembly that it supports.

You can also benefit from the slow-motion knobs that enable you to more precisely identify, point, and follow objects as they move across the sky.

Whether this is planets, the moon, or the brighter start galaxies.

The Explorascope 114az is delivered in a concise well-padded box.

Setting up the telescope is simple, taking only a matter of minutes, even for complete newbies who have not set up a telescope before. 

At a total weight of 6.7 pounds, it’s ideal for impromptu observing sessions or transporting with you on the go.

Regarding observations, one of the major benefits is that you get an erect image diagonal included which provides correct image orientation.

Basically, you can observe objects the right way up and the right way round.

Images are not inverted unlike a lot of other telescopes on the market.

On all objects, whether it is the Moon or planets like Jupiter, you’ll get fantastic clear and concise views.

The Explorascope at low power (22 or 44x) is great to scan the sky with.

The field of view at 44x is 1 degree, and even wider at 22x.

There’s a lot of stars you can see with this setup.

What Is A Newtonian Reflector Telescope?

The Celestron Explorascope is a Newtonian Reflector, so it’s good to know what this is actually is and how it works.

A reflecting telescope, sometimes just referred to as a Reflector – is designed with a simple set of optics and a combination of mirrors that form images by ‘reflecting’ light. They typically sit on Alt-Azimuth and Equatorial Mounts.

The Optical Tube Assembly has a primary parabolic mirror and a flat secondary mirror, then there is the focuser (an eyepiece) that is included on the side.

Light enters the optical tube, bounces off the primary mirror at the foot of the telescope, and is then focused onto the flatter secondary mirror.

This is then placed through the eyepiece.

The first reflecting telescope was invented by Sir Isaac Newton – it was the first real alternative to the refractive telescope.

The purpose was to overcome what is known as chromatic aberrations that typically occurs in Refractive Telescopes (when a lens is cannot focus all of the required colors at a single point.)

Newtonian telescopes are very versatile and are considered ideal for both amateurs and professional astronomers. They are normally very cost-effective when compared to other telescopes.

Newtonian Reflector Pros

✔️ Enhanced light-gathering ability. With more light collected, fainter celestial objects can be observed.

✔️ Cheaper to the manufacturer which makes them generally more affordable.

✔️ Operate via a Mount. The Alt-Azimuth of the Explorascope 114az enables manual movement by hand and the Altitude (up/down) and Azimuth (left/right) axis.

Newtonian Reflector Cons

❌ Slightly more expensive than a Newtonian Telescope that has a similar Aperture.

❌ Unless a GoTo Mount is used, manual adjustments are required when tracking celestial objects.

❌ Lower contrast compared to Refractors of equal power and size

❌ Thermal air currents are possible, which can affect the quality of the image

What Is An Alt-Azimuth Mount?

An Altazimuth Mount (sometimes called an Alt-Az/AZ) is one of the most common types of mount due to its user-friendliness and ease of use.

It has a simple straightforward design and how you need to operate it. There are two axes – the altitude (vertical) and azimuth (horizontal) axis which need to be maneuvered.

This mount enables you to move the telescope in two directions, whether this be up and down or side to side.

The better models provide knobs that you can alter in slow motion. This enables you to make minor adjustments which make it easier to observe and follow objects in the sky.

There’s an element of freedom using an Alt-Az mount and telescope.
