Celestron Nexstar 130 Slt Vs Celestron Nexstar 6Se-

Purchasing a telescope is a delicate process that requires patience, a lot of research and honest advice. Regardless of whether you are a beginner or professional, you must put many considerations into this decision. Take a look at CELESTRON NEXSTAR 130 SLT VS CELESTRON NEXSTAR 6SE for a review on two different styles of telescopes each with its own working principles, pros and cons.

Being a teacher has its perks, and the biggest one is introducing your students to ideas and concepts that change their lives. I am teacher of physics, but the biggest astronomy enthusiast you might ever meet. Often, my students approach me for advice regarding various telescope issues and purchases. One of the most complex issues I’ve helped hundreds of students figure out is buying their first telescopes. While some of them are absolute beginners, others aren’t: hence the reason for this guide. I am going to compare 2 of my top options for beginner to intermediate level telescopes. Both these models are finely crafted instruments that deserve the utmost care, and not just because telescopes can get pricey. For more on finding a suitable telescope, maintaining it and choosing the right model, take a look at CELESTRON NEXSTAR 130 SLT VS CELESTRON NEXSTAR 6SE.

What are the differences between the CELESTRON NEXSTAR 130 SLT and the CELESTRON NEXSTAR 6SE?

Design and family

Because they are from different lines, the SLT 130 and the 6SE have very obvious differences in their design and aesthetics. For example, the 130 SLT comes from the SLT Star location telescope that combines high quality optics, user friendly, fully automated interface and sturdy mounting into an all black compact series of telescopes. Alternatively, the 6SE comes from the orange tube line that is one of Celestron’s most striking lines. This series of telescopes combines excellent optics at reasonable prices for anyone from beginner to advanced user.

Additionally, the 130SLT utilizes lenses instead of mirrors as it is a Newtonian reflector telescope. With this design, you can rely on the instrument to deliver bright colored images over a wide field. However, these aren’t obvious at first glance. The 6SE on the other hand is a Schmidt Cassegrain telescope that uses both mirrors and lenses. The most obvious design difference however is the optical tube. Because the 130 SLT belongs to a different series of scopes compared to the 6SE, it has a different look to it. It is an all black telescope with an aluminum optical tube and reliable mounts. Alternatively, the 6SE is part of the Orange tube series, which obviously, have an orange optical tube. Dimensions of the 6SE are larger than the 130 SLT but we will save that for later.


The way mirrors, lenses or mirrors and lenses are arranged and placed in a telescope will influence its operating principles and many other aspects of the device. In our case, the Celestron 130 SLT is a different telescope type from the NexStar 6SE: Newtonian vs. Schmidt-Cassegrains types respectively.

Newtonian reflector design of telescopes is an open tube telescope with the primary mirror located at the rear end of the optical tube. They rely on this primary mirror to gather and focus the incoming light on the angularly placed secondary mirror which then reflects the image to a focuser whereby it can be viewed from the eyepiece. Alternatively, the Schmidt Cassegrain style telescope is a compound style telescope which both mirrors and lenses to manipulate the optics to form an image. Light enters through the aspheric Schmidt correcting lens after which it hits the primary mirror and becomes reflected upwards where it is intercepted by a secondary mirror. Finally, the light is reflected out through an opening at the back of the device and the image formed on the eye piece. However, just like the Newtonian design, the Cassegrain design is also quite popular for use on beginner level telescopes. This catadioptric design utilizes mirrors to produce the image, as does the Newtonian reflector.

Weight and overall size

Including the tripod, the 130SLT weighs 18lbs while the 6SE weighs 30lbs. Although the 6SE is substantially heavier than the 130 SLT, BOTH of these weights fall within comfortable ranges. They contribute positively to the ‘easy to use’ characteristic on many of Celestron’s models.

TIP: Unless you plan on taking this telescope everywhere with you, weight should be a major issue when choosing between telescopes.


Mounts in telescopes are another essential element to telescope because they will influence the way the instrument moves. Both the 130 SLT and the 6SE are equipped with Alt-Az mounts. This is a pretty basic form of mounting many telescopes use. Both are fully computerized and enabled with the unique single fork arm mount from Celestron.


Magnification plays an important part in telescope capabilities. Upon evaluation, you will notice many telescopes come with eyepiece(s) as part of the accessories. Using these eye pieces, you can adjust magnification as you see fit. However, there is a threshold as to how much and how little you should adjust the magnification. Over magnifying for example can cause the image to blur and get worse. Optimal magnification depends on many things including the type of eyepiece on your telescope or even atmospheric conditions. The 130SLT delivers a basic 26X-72X magnification. Additionally, it has the capacity to achieve 307X as its highest useful magnification. The 6SE on the other hand has a standard 60X magnification but 354X as the highest possible magnification.

Because of the additional 9mm eyepiece, the Celestron 130 SLT has some magnification variety but cannot achieve as large enough a magnification as the 6SE can.


Yes, Celestron does throw in some freebies for all their users to enjoy. One of these is the Special Edition Astronomy Starry night astronomy software. You will enjoy access to a 36k celestial object database from which you can print maps, or even renderings of stars, planets or galaxies in 3D. Additionally, getting the 130 SLT grants you access to Sky Align for easy alignment and Star sense tech. The Celestron 6SE comes with even more freebies compared to the 130 SLT. On top of this, the 6SE includes the patented Star Bright XLT coating. All star polar alignment and is compatible with CPWI and Fastar. These are Celestron based technologies that are meant to enhance your astronomy experience.
