The popularity of Celestron's NexStar 114 models inspired us to go bigger! Celestron is proud to introduce NexStar 130 SLT. The NexStar 130 SLT has 30% more light-gathering power than our 114mm telescope. And the 114 SLT, like the other models in the SLT Series, comes with a.

A few keystrokes on the NexStar hand control automatically slews the NexStar 130 SLT to any of those 4,033 objects, including over 600 galaxies, 300 star clusters, and dozens of beautiful binary stars. The computer's software can be flash upgraded via the internet so you will always have the most up-to-date software version available.
Celestron NexStar 130 SLT is very popular telescope amongst the beginners, so I have decided to do a complete review of this telescope. I have already made a review of an almost identical telescope from SkyWatcher. In the past, I was considering buying both these telescopes, so I know them well. Let’s talk about the Celestron NexStar 130 SLT today.
Celestron NexStar 130 SLT is reflecting computerized telescope. Reflecting telescopes are well known for their affordable price. Reflectors are using mirrors to produce image and are cheaper to manufacture than lenses in refracting telescopes. Because of that, you will always get much better performance for the money when you buy a reflecting telescope like this one.
AFFILIATE DISCLOSURE: I hope you love the products I recommend! Just so you know, I may collect a share of sales or other compensation from the links on this page. Thank you very much if you use my links, I really appreciate it.
This telescope is also on the computerized mount which is helpful with finding objects on the night sky- a great feature if you are a beginner and you don’t know anything about astronomy yet. And another great thing is that the Celestron brand is one of the top telescope manufacturers in the world so you can’t go wrong here. The customer service is amazing, and the build quality is very high.
Specifications
As I said before, it is a Newtonian Reflector with two mirrors. One is a small secondary mirror at the front of the optical tube mounted on a spider mount. It is tilted 45 degrees to reflect the light from the primary mirror at the back to the eyepiece. The diameter of the primary mirror in the Celestron NexStar 130 SLT is 130mm as you can see in the name of the telescope. It is a high quality multicoated parabolic mirror providing excellent and crisp images. The diameter(aperture) of 130mm delivers 30% more light gathering than 114mm mirror used in smaller Celestron models.
The focal length of this telescope is 650mm. It is the distance from the primary mirror to the focal point in the focuser. This is a fast F5 (divide 650 by 130) telescope. It means that it is very good for faint objects like nebulas or galaxies. If your telescope is slow like F10, it will not perform as good as F5 on fainter objects, and you will see fewer details.

Old vs. New
There are two models of this telescope available, the older one and the new one. You can come across both when you are looking to buy one but don’t panic they are exactly the same. The only difference is in the hand controller. The newer version has different descriptions on the buttons, and the buttons have slightly different positions.
Dns for software update mac os. What I like about the newer hand controller is that the buttons are shaped for a feel. This is a massive advantage in the night when you are trying to control the telescope in the dark, and you can feel different shapes of the buttons, so you don’t press the wrong button accidentally.
For example, the arrow buttons have little barriers on the sides so when moving the telescope in the dark; you don’t have to worry about pressing enter or ESC accidentally as it happened to me many times with the old controller.
Pros
- cost: it is an affordable telescope with a decent aperture and computerized mount, there is no competition for it in that class. You can check the current price on Amazon.
- easy to use: after a few moments with the controller, you will learn everything you need to know to control the telescope. It is very intuitive and easily operated instrument.
- lightweight: it only weighs 17 pounds so you can move it with one hand. You can also separate the optical tube and the mount very quickly and put it in the car, which makes it highly portable and convenient.
- mirror: the primary is aluminum coated high-quality parabolic mirror
- 2″ Focuser: you can use 2″ eyepieces with provided adapter. It is a unique feature in this class of telescope because many of them don’t have that option and you can only use 1.25″ eyepieces.
- dependable: a very durable telescope that will last you forever if you take good care of it.
- holds collimation: many reflecting telescopes have a problem to hold the collimation. Sometimes you have to collimate a few times at night, but this one will stay collimated for many nights.
- good support: it is a Celestron which means the support for this telescope is on the high level (customer service, manuals, etc.)
Cons
- parts: sometimes, it can be a problem to find parts for it, like when you break the holder tray, etc.
- red dot finder not working: some users reported that the red dot finder is not working or it will stop working after a while. But Celestron will promptly replace the faulty one, so no stress.
- no astrophotography: if you are planning to do astrophotography, this is not the telescope you want. However, you can still do simple planetary or Moon astrophotography. It is just not suitable for deep sky objects.
Eyepieces(lenses) and Magnification
The Celestron NexStar 130 SLT comes with two plossl eyepieces. The focal lengths are 25mm and 9mm, which gives you two magnifications. With 25mm eyepiece you get 26x magnification, and with the 9mm you are looking at 72x magnification. You have to upgrade the eyepiece collection if you want more magnification. Or you can use a Barlow lens that will double or triple the magnification provided with each eyepiece, but it will slightly decrease the quality of the image.
It is very easy to calculate the magnification. You have to divide the focal length of the telescope with the focal length of the eyepiece you are currently using. That’s why you get 26x magnification with the 25mm eyepiece. Just divide 650 with 25.
But don’t overdo it. For every telescope, there is maximal useful magnification, and the limit depends on the size of the aperture. In this case, with an aperture of 130mm, the maximal useful magnification is 260x. To get that number, you multiply the size of the aperture by two(130×2=260). If you go over that, the image will be blurry, and you won’t be able to focus properly.

Celestron StarPointer – Red Dot Finder
The telescope comes with the red dot finder. It is a small finders scope with no magnification that helps to locate the object on the sky. It has a small lens at the front, and little red LED light. This LED is shining on the lens, making a small red dot in the middle of the lens. That’s why it’s called red dot finder.
It is a very common tool in telescopes in the lower class. The first thing you have to is to align it with the optical tube, so when you are looking through it, and the red dot is on the object, you want to see the same object in the eyepiece of the telescope. I suggest you do it during the day before the stargazing night. Just point it on the tree or something as a reference and adjust the LED dot with the small knobs until you see the same image in the finder and the eyepiece. It can be frustrating to align it at night, so don’t forget to do it.
In my opinion, the small finder scopes with the crosshair are better because they are actually small scopes and are more accurate, but the red dot finder will do the job, and you can always upgrade it later to proper finderscope.
Computerized Mount
The computerized mount is an excellent feature on a telescope. You don’t have to spend time looking for objects manually. The only thing you have to do here is to press the button, and the telescope will automatically slew to the object. The hand controller has over 4000 objects in the database and also the tour feature of the best current objects on the sky, so it is a pleasure to use it. This is a big advantage of the computerized mount, and beginners will enjoy it. The computerized mount of the Celestron NexStar 130 SLT is easy to use, and you will learn how to operate it in a few sessions. Celestron also has a very informative guide in the box, so read it first. Also, it might be a good idea to play with it during the day to get used to it.
The thing that scares people off the computerized mounts is the star alignment which you have to do before every stargazing session. But it is a very easy process. However, you need to know the positions of the brightest stars on the sky. This, you can easily find in any planetarium software or mobile app.
Celestron is using SkyAlign with three bright objects to align the telescope. You might struggle the first time, but you will learn it quickly. You can have a look on my computerized guide article where I explain in detail the process, and I also mention a few tips on how to improve the star alignment.
The mount is powered by 8xAA Batteries that are not included. The battery tray is conveniently placed in the arm of the mount. This is a nice feature because, for example, with the SkyWatcher model you have funny battery bag hanging of the telescope. You can also buy a separate 12 VDC adapter if you are in the proximity of electrical outlet. Otherwise, the batteries are enough for an outdoor session, and they last long. If you want to be on the safer side, bring some spare ones with you.
Celestron SkyPortal WiFi Module Upgrade
This is a very cool gadget. The Celestron SkyPortal WiFi Module is an upgrade of your already amazing computerized mount. It is a small device that you plug into the AUX port of the mount, and it will create your own WIFI network. You can connect to that network with your smartphone or tablet. But first, you have to download the SkyPortal app for Android or iOS.
What it does is to allow you to control the telescope wirelessly. It contains over 100 000 objects in the database, and the interface of the app is amazing. You can also point your device to the sky and see a real-time projection of the objects on the sky. You just tap on the object, and the telescope will point on it automatically. Watch the short video below to get a better idea of what it is about.
Tripod
And now, the tripod of the Celestron NexStar 130 SLT. Some people complain that it is not sturdy and the telescope vibrates a lot. But I think that it is a good tripod for the price you are paying. It has sturdy steel legs; the tripod is foldable and easy to transport and assemble. You will get some vibrations when touching the telescope but wait a few seconds, and the vibrations will stop.
To improve stability, I always hang something heavy in the middle to lower the center of gravity. Remember not to hang it on the middle holder tray legs because you will break it. Do it on the top where legs are joined to the top part of the mount. It will greatly improve the stability and performance of the tripod. Another tip is to have the telescope at the lowest position possible. Don’t extend the legs if you don’t have to, and the stability will be much better.
Collimation
With reflecting telescopes, you always have to collimate. The collimation is a simple process of aligning the mirrors of the telescope. Bad collimation can result in the blurry image or focusing problems. Many people are scared of it but don’t be. The telescopes come collimated from the factory, but sometimes the collimation is out, so it is a good idea to check it.
You can buy a laser collimation tool that will do the job in seconds. All you have to do is to play with the adjustment knobs of the primary mirror. The secondary mirror is rarely off, so I wouldn’t touch it if you don’t see any issues. I have created a complex guide for collimation of the reflector without the tools, so go and read it.
Astrophotography
Celestron NexStar 130 SLT is not suited for the deep sky astrophotography. There are two main problems. You will not be able to reach focus with the DSLR camera, and because of the Alt-Azimuth mount, you are limited to only 30-40s exposures. But I have done it anyway. I have modified my SkyWatcher model that is the same telescope as Celestron NexStar 130 SLT, and I was successful. It is limiting, but possible. You can do a nice picture of some bright deep sky objects. As an example, here is the Orion nebula I captured. You can learn more about it here, and more pictures are available in my Reddit post.
However, you can absolutely do the planetary or Moon astrophotography and video astronomy without any modification of the telescope. All you need to do is to use a specialized astronomy camera or simple webcam. I have written an article on how to use a webcam with the telescope, so if you are interested, you can check it out.
Final Thoughts
I think that Celestron NexStar 130 SLT is a great telescope and I also recommend it for beginners. It is very affordable and fun to use. It will show you almost everything in the night sky. I was using the telescope for a few years, and I was very happy with it. If this is the first telescope that you are considering to buy, go for it. It is the cheapest computerized telescope with an aperture big enough to satisfy any hobbyist astronomer out there.
Firmware Versions on the NexStar SLT Series
Non-English Hand Control Owners - read this. The |
NexStar SLT scopes have two sets of processors. There are processors in the hand control (HC) and there are processors in the base of the scope in a section known as the motor control (MC). The MC firmware can be updated by the owner (read this).
There have been two versions of hand control available for the SLT:
- Hand control version 4.X. This hand control can be updated by the owner. Read this for step by step instructions on upgrading the firmware.
- The NexStar+ hand control. This hand control can be updated by the owner and began shipping with new SLT scopes in January 2012. It is also available for purchase since February 2012. Read this for info on this new hand control and this for step by step instructions on upgrading the firmware.
For additional details about features on newer versions, check the Manuals section of this web site.

Version 4 Hand Control (firmware files are named SLT or SLT_LCM)
Note: It is possible to use the NXS firmware on the NexStar SLT. This will provide EQ alignment routines useful if you have fashioned a way to polar align (use of a wedge) your SLT scope.
- 4.22 - Fixes the date when the scope is used with a GPS receiver that returns a date 20 years in the past.
- 4.21 - Fixed the RS-232 negative declination bug found in 4.20.
- 4.20 - This version has a bug - if you connect a computer/PDA/smart phone to the RS-232 port and direct a GoTo to an object with negative declination, the scope will instead point to +90 declination. It is recommended you upgrade to 4.21 or higher. Fixed an error in the GoTo RA-Dec menu item. Hand Control now reports immediately if the are communication ('No Response') difficulties at start up. No Response errors now give a 'Press UNDO to continue' option. For mounts with a GPS module in use, changed the messages displayed to clarify when the GPS was still attempting a link and when it was successful.
- 4.17- An important upgrade with many new features and fixes. The hand control now calculates positions with respect to precession - in other words, previously all coordinates were J2000 while this version uses JNow. Fixes problems with Southern Hemisphere alignments. Pressing ALIGN while in the Named Stars menu now takes you to the Align menu. If there is no GPS module, changes the initial alignment to always prompt for the date and time. Sets slew rate to 5 upon waking from hibernation. The Factory Settings menu item now resets all motor control settings (as well as the hand control settings) and will force the user to restart the system. The hand control is now locked when performing a motor control upgrade via the port on the bottom of the hand control. Added two PC control commands: one to undo any current 'Sync', the other to retrieve the local sidereal time from the hand control. Fixed error when using SAO stars (selected from the STAR button) as alignment objects. Fixes a bug which changes rate if a direction button is pressed after the RATE button. Fixes a rare problem updating the motor control through the hand control.
- 4.13 - This version allows the motor control (MC) firmware to be upgraded via the port on the bottom of the hand control.
- 4.12 - The most significant change in this version is variable brightness control for the display and buttons - values are from 0 (off) to 8 (full brightness). There is also a fix that reduces (but does not eliminate) the chance that the display comes up blank the first time you power up, a problem much more prevalent in cold weather. The fix on those occasions when it does still come up blank remains the same - turn off the power, wait a couple of seconds and turn on the power again. The Version menu item has been changed - it now displays the mount model after displaying the HC and MC versions. This version is also the first to support the new NexStar SE mounts.
- 4.10 - The most significant change in this version is Sync. Sync is available both via the hand control and via PC software (TheSky, Starry Night, etc.). This provides very accurate GoTo pointing in the area of the sky where the Sync is performed and it allows the PC software to match with the actual position the scope is pointed to. Other new features/improvements: Calibrate Goto (help to improve GoTo accuracy) and general pointing accuracy improvement.
- 4.03 - Original version for the NexStar SLT.
MC Versions
- 5.18 - The final GoTo approach is now faster and quieter.
- 5.14 - Corrects a problem with the cordwrap prevention feature.
- 5.09 - Original version for the NexStar SLT.
