Celestron NexStar 114 SLT VS Celestron NexStar 130 SLT

Interested in a Celestron telescope but don’t know where to start? Do not worry, Celestron has a bunch of great telescope options, to suit different needs beginners may have. The SLT line is particularly beginner friendly and a good choice for anyone’s first telescope. Take a look at Celestron NexStar 114 SLT VS Celestron NexStar 130 SLT which will compare two of the SLT lines’ favorites especially for beginner users.

One of the most frightening things I’ve ever had to do was purchase my first telescope. Even though it was a used instrument with some flaws, it took me days and many sleepless nights to decide that I wanted it. It has been 14 years since then, but my love and appreciation for telescopes has only grown. In fact, it drove me to pursue and teach college level physics where I run the astronomy club. I often encourage students seeking to make a major telescope purchase to consider many things and many times, guide them though the search and selection process. The most difficult part about finding the right telescope is combing through all the information to ensure the features are right for you. Among Celestron’s various series of telescopes, the SLT is a great place for beginners and a popular starting point for many of my students. The line carries easy to use, but well equipped instruments any beginner will not only enjoy but also find quite reliable. The popular 114 SLT and 130 SLT both from this line are going to be the focus of this view. I will be comparing each model to the other, determine the differences between both options and thoroughly review what either telescope has to offer. Here is Celestron NexStar 114 SLT VS Celestron NexStar 130 SLT for further insight.

What are the differences between the Celestron NexStar 114 SLT and the Celestron NexStar 130 SLT?

Celestron NexStar 114 Slt Vs Celestron NexStar 130 SLT – How they compare


Both the 114 and 130 SLT are Newtonian style telescopes that operate by reflecting gathered light to allow the user to view the synthesized image. If you are new to telescopes, then you might not be aware of these existing differences between the various types of telescopes there are. For this particular case, you need only know that telescopes are divided into 3 basic groups using their operating principle as the distinguishing factors. These groups include refractor style, reflector style and compound style telescopes.

While they may be similar in that sense, the 114 and 130 SLT have quite distinct optics. Important numbers such as the aperture, focal length and focal ratio on either option varies greatly. The Celestron NexStar 114 SLT for instance has a 114mm (4.48″) Aperture, with a 450mm Focal length, and f/3.95 Focal ratio. Alternatively, the Celestron NexStar 130 SLT has a 130mm Aperture, 1500mm Focal length, and f/12.5 Focal ratio. These differences will influence optical capabilities in terms of what celestial objects you can see and how clearly you can see them.

TIP: It is important to know that in many instances, a change in aperture size will affect overall weight of the telescope. Because the 130 SLT has a larger aperture than the 114 SLT, it is slightly heavier than the 114 SLT. The best telescope for beginners is one which anybody can set up, or move about with ease. Luckily, both the 114 SLT and 130 SLT are compact, easy to use lightweight instruments.
