Celestron Nexstar 130 Slt Vs Celestron Nexstar 4Se

Your first telescope is an important purchase that cannot be made on a whim. There are many principles that you must understand before you commit to any brand. Here, you will find a guide to two popular Celestron telescopes, both fundamentally different but each very functional. Take a look at CELESTRON NEXSTAR 130 SLT VS CELESTRON NEXSTAR 4SE, for an unbiased analysis of what either of these has to offer.

I come from a family of astronomers and many astronomy enthusiasts, so I have had my fair experience with vetting and purchasing of telescopes. Coupled with a career in astronomy it is fair to say I have a deep appreciation and understanding of telescopes. One of my favorite things to do is meeting beginner users or amateur s to astronomy and sky gazing because I can introduce them to all the wonders outside the scope of our planet.

The most popular question after these interactions if often, what kind of telescope I would recommend to start out or even more insight on telescopes to help make this important choice. My top two favorite options for beginner telescopes are both by Celestron but from different lines: the SLT (Star Locating Telescope) and the SE series. Both these telescopes are designed with beginners and intermediate users in mind, making them ideal for either category. Here is CELESTRON NEXSTAR 130 SLT VS CELESTRON NEXSTAR 4SE for further insight.

CELESTRON NEXSTAR 130 SLT VS CELESTRON NEXSTAR 4SE- How do these telescopes compare?

Below is a detailed comparison of some of the key differences and some similarities between the CELESTRON NEXSTAR 130 SLT VS CELESTRON NEXSTAR 4SE.

Features for beginners

This wouldn’t be a useful telescope for beginners guide if it didn’t highlight and compare the amateur features that make these telescopes useful for beginners. The CELESTRON NEXSTAR 130 SLT comes with an easy to use mount, and a quick release arm mount among other design integrations that make it great for beginners. This telescope is ideal for users interested in terrestrial or even celestial observing. On the other hand, The CELESTRON NEXSTAR 4SE is enabled with automated features making the telescope quite easy to use.

Working principles

Telescopes are divided into different types based on many criteria, among which the most important is the working principle. The CELTRON NexStar 130 SLT for example, is a Newtonian refractor style telescope, Maksutov-Cassegrain scopes are telescopes that are considered hybrids. They operate by a combination of mirrors and lenses. The CELTRON NexStar 4SE is this sort of telescope which combines benefits of a low cost and high quality refractor.


When talking about telescopes, there are many aspects to think about. However, the telescope optics is among the most important part of the telescope. The way the lenses or mirrors or both are arranged will affect the entire telescope. In terms of optics, the CELESTRON 130 SLT, Aperture 130mm, 650mm Focal length, f/5 Focal ratio and 26X, 72X magnification. On the other hand, the 4SE includes an Aperture 102mm or 4 inches, 1325mm Focal length, f/13 Focal ratio and 241X, 15X as highest and lowest useful magnification.


Alt-Az, as it is commonly known is an altitude azimuth mount is name d so because it uses 2 motions to follow objects across the sky. The Azimuth motion allows the telescope to track southerly stars form. Altitude lifts your scope as it follows an object or star to its highest elevation and then lowers in again. Interestingly, this mount uses a single fork rather than a double design many other Alt-Az mount utilize. On the other hand: the NexStar 4SE utilizes Enabled with the Sky Align feature, beginners can rely on the telescope to align itself.

Both these telescopes utilize a single fork arm mount feature which is a patented design that perfectly combines all the elements of a great mount. The result is a simple to transport, easy to set up and straightforward use mount.


Yes, there are some free perks accommodated within this purchase among our favorite is the Starry night software. With access to this database, you won’t simply use the telescope, but learn from it using vetted and well celebrated astronomy software.

Celestron equips some of its computerized telescopes with this software for the benefit of its users. Models from the SE line, which the NexStar 4SE is part off, allow users to access the 40K object database while the 130 SLT allows access to the 36k object database. Moreover, this instrument comes with a sturdily built stainless steel tripod for all your set up needs.

Power requirements

The Celestron 4SE utilizes rechargeable AA batteries or the alternative twelve VDC-750mA option as a power source. Similarly, the Celestron 130 SLT uses the 12 VDC option or eight double A batteries which are usually not included with the purchase.

Frequently asked questions

What is a computerized telescope?

These are telescopes utilizing various technologies to make the alignment, tracking or even location of celestial objects easy and convenient. Depending on the extent to which the telescope is technologically enabled, you can find different celestial objects with just the press of a button. This is unlike manual instruments that require an entire process dedicated to the set up.

Can the 130 SLT be used for astrophotography?

Yes and No. While many know this model as one centered on planetary imaging, some users have been able to utilize this scope for deep space astrophotography. The NexImage Solar System Imager for example only takes picture of planets making it difficult to capture deep space objects. However, with the right modifications or additions, it could be possible to use this telescope to photograph deep sky objects.

How long does a 130 SLT last you?

Good telescopes are built to last you a life time, or until you can’t do anything new or exciting with them anymore. Beginners especially tend to outgrow poorly featured telescopes pretty quickly. The SLT 130 is made of quality material and advanced technologies to last you as long as you intend to use it.
