If you’re a stargazing enthusiast, then you should definitely check out our Celestron NexStar 127 SLT telescope review. Combining only the best Celestron has to offer, the NexStar 127 SLT telescope is a great way to begin your journey to the stars.
The main thing that distinguishes this Celestron NexStar model from other computerized scopes is its high-quality multi-coated optics, which enables the viewer to make fine observations.
With this scope, you can see Saturn’s rings as clearly as the Moon’s craters.
What Is the Celestron NexStar 127 SLT Telescope?
Compared to other telescopes we’ve covered in our reviews, most of which fall under the refractor or reflector telescope category, the Celestron NexStar 127 SLT is a bit special since it sports a Maksutov-Cassegrain design.
Maksutov-Cassegrain telescopes, also known as catadioptric telescopes, are far more versatile than reflector or refractor ones.
They are mostly hailed for their excellent near focus capabilities. Since the optics and light-gathering systems are more advanced than those of a reflector or refracting scope, catadioptric scopes are excellent for observing binary star systems or for astrophotography.
Another advantage of Maksutov-Cassegrain scopes is that they are much more durable and compact than Newtonian scopes. But this difference in performance is directly reflected in the cost of the product, meaning that Maksutov-Cassegrain designs are much more expensive than Schmidt-Cassegrain scopes.
Furthermore, due to its close-tube design, the NexStar 127SLT telescope produces higher quality images without the user having to compensate for degrading air current.
Traditionally, SLT computerized telescopes are very difficult to set up and to calibrate. However, this is not the case with the Celestron NexStar 127 SLT model.
When putting together this great piece of equipment, Celestron thought that a good telescope would be welcome, but customers need an easy-to-use telescope as well.
Thanks to the no-tools technology, the Celestron NexStar 127 SLT can be assembled in less than 10 minutes. Thanks to the provided user manual, any newbie can align the telescope without having to consult any videos or written tutorials first

As part of our Celestron NexStar 127 SLT telescope review, we had the chance of taking a closer look at its optical features. The first thing that we’ve observed is that the 127 SLT has a wide 127mm aperture, which can easily cover a 0.83-degree field of view.
The scope’s focal length is 1500mm, and it has a focal ratio of f/12. As far as eyepieces are concerned, each Celestron NexStar 127 SLT telescope comes with a 25mm eyepiece and a 9mm eyepiece, having a maximum magnification of 167x with the default 9 mm eyepiece.
The Celestron NexStar 127 SLT telescope stands on top of a Motorized Altazimuth mount, which can be controlled via the provided digital hand controller.
Alternatively, the mount can be hooked to a computer for increased precision. With the 127 SLT, you can see the Moon in detail, but also Jupiter, Venus, and other deep-space objects.
The NexStar 127SLT does not require special care. Users just need to use it reasonably, and carefully store it away from the sun and moisture. The optical elements should get special attention. Users should handle them very carefully, paying attention not to touch the lens or mirrors.

Warranty And Guarantee Information
The manufacturer offers a 2-year product warranty for the NexStar 127 SLT telescope. Keep the proof-of-purchase in a safe place throughout the warranty period, as you will need it in case you want Celestron to repair or replace your scope.

To conclude our Celestron NexStar 127 SLT telescope review, we should add in a few words about this telescope. As far as our team is concerned, this was the best computerized mount telescope we’ve ever had the privilege to test out.
The hand controller on the mount lets you control the 127 Mak SLT with increased precision, compared to regular hand-driven Dobsonian on Newtonian designs.
Furthermore, we’ve actually managed to set quite a record with this telescope: it took us no more than 10 minutes to set it up and to align it only by using the manual included in the package.
The eyepieces included in the pack were enough for viewing the Moon’s craters or observing nebulas, but you can always increase the quality of your observation by buying the additional accessories kit.
The Moon filter was pretty useful at trimming out the excess light, especially if you use the telescope in the city.
All in all, the Celestron 127 SLT is a sturdy piece of equipment, and very easy-to-use. Moreover, thanks to its no-tools setup, every user, regardless of his or her experience, can set it up without consulting any additional materials.
