Celestron Powerseeker 127eq Review

Last Updated: 28.03.20



Main advantage


The Powerseeker 127eq is aimed at amateur astronomers who are looking to buy their first telescope and want a product that is affordable and can offer the performance needed to explore the beauty of the night sky. It is one of the most popular entry-level Newtonian reflector telescopes currently on the market.

This model performs very well and it is a beautiful instrument to behold, and truth be told, we expected nothing less from one of the most appreciated telescope manufacturers. It is part of the popular Powerseeker series which is specifically designed for aspiring astronomers and it delivers impressive value for money.

The telescope is very easy to use and portable, which means that the entire family can gather around it to explore the night sky since it can deliver crisp views of the Moon, Jupiter’s Galilean moons and the breathtaking rings of Saturn.

Once you get more used to it you can also turn the objective to distant celestial bodies and go beyond our solar system to explore the Orion Nebula, the Andromeda Galaxy and many more.

Thus, if you’re in the market for an affordable entry-level telescope that can deliver great performance, the Celestron Powerseeker 127eq is a good start for any amateur stargazer.


Main disadvantage


Although this is a great scope that should please any amateur astronomer, it does have a small quirk that you should be aware of before buying and that we will explore right now. While the Newtonian Reflector design is one of the main advantages of this option since it produces exquisite images, it also comes with a small disadvantage.

For first time users, Newtonian Reflectors can take a bit of time to get familiar with aligning them (collimation). The process may take you a while to figure out but once you do, it shouldn’t take you more than a couple of seconds to check and fine-tune the telescope before each use.

You need to be equipped with a lot of patience or have someone more experienced with you to guide you through the process of collimation. The good thing is that the instruction manual is very helpful and the internet is now full of free resources with step-by-step guides and video tutorials about collimation that will be very useful for any beginner who’s keen to learn.

Other than that, there is little else to say against this model once we take into account its low price point and the fact that it is aimed mainly at beginners.

Main features explained


Great optics

The Powerseeker 127eq is a Newtonian Reflector and that means that it uses mirrors to gather light from the objects you are observing and then it reflects the light back to your eyes. The advantage of this option is that unlike glass lenses, mirrors are much less expensive to produce and that helps the manufacturer keep the price as low as possible.

While a Newtonian Reflector is indeed cheaper to produce, it doesn’t necessarily mean that the performance it offers is worse, quite the contrary. This design offers more value in terms of inches of aperture and the larger the aperture is, the clearer and more precise your view will be.

This option has an aperture of 127mm (5 inches) which is good for a starter to intermediate scope and it will allow you to get superb views of the Moon surface in great detail as well as bright planets, star clusters, and nebulas.

Even with a large aperture, a telescope still needs top-quality optical elements and the Celestron model features optical components made from fully coated glass with high-transmission aluminum. They help give more refinement and definition and are a sign of a high quality and premium design.



Portable and easy to use

The telescope is designed to be used by adults and kids alike, which is why it comes in a very compact, lightweight, and portable form factor. You can take it with you at your favorite campsite, dark sky observing site or you can just take it out in the backyard to have fun with the entire family.

While it is by no means the lightest option on the market, it certainly won’t weigh you down. Once you have it fully assembled with all the accessories you get in the pack, the unit will weigh only around 28 pounds. As far as size is concerned, it is not large at all so you’ll have no problem transporting it in your car.

Additionally, you won’t need any tool to mount this telescope and the assembly process can be completed in a matter of minutes and it is extremely easy to get a grasp of it. Beginners, in particular, will certainly appreciate this aspect and if you have any issues, you can use the included instruction manual.

There is also a link to an instruction video made by Celestron for people who find it much easier to follow video instructions as opposed to printed ones.


Equatorial mount

As any seasoned astronomer will probably notice from the “EQ” present in the product name, the Celestron Powerseeker 127eq comes fitted with an equatorial mount that will enable you to track the stars and other celestial bodies and compensate for the Earth’s rotation so that you don’t lose sight of what you’re observing.

Once you find the celestial body that you wish to explore, you simply need to move the axis of the mount left/right to keep it in your eyepiece. When compared to standard Alt-Azimuth tripods that need to be moved constantly up and down, and left and right to track an object, this option provides a much better experience for beginners.

The main issue with an equatorial mount is that it can be a bit confusing to align for the first time. The mount relies on equatorial movement and in order for it to provide accurate results, it needs to be aligned to the celestial pole star. It does sound a bit confusing, but there’s no need to worry too much about it.

Celestron has included detailed instructions on this matter and you can also find tons of video tutorials online that will show you everything you need to know about how to set up an equatorial mount the right way.
