Product Description

Style: 130 SLT Newtonian

Product Description

The nexstar 130 slt, like the other models in the slt Series, comes with a fully computerized hand control that gives you the ability to automatically slew to any of its 4,000+ objects, including over 600 galaxies, 300 clusters and dozens of beautiful binary stars. With its pre-assembled, adjustable steel tripod, quick release fork arm mount, and accessory tray, the nexstar 130 slt can be up and ready to use in a matter of minutes with no tools needed. The sky align alignment technology and the included star pointer finder scope with a Red LED, makes aligning a breeze. View the details of the lunar surface, the rings of Saturn, the polar ice caps on mars, the cloud belts on Jupiter or a number of the Messier objects using the additional light-gathering capabilities of the 130 slt's 5 inch primary mirror. Because of the Newtonian design, the mirror gives fully color-corrected views that are best suited for astronomical use. The internal battery compartment prevents cord wrap during use and Auxiliary Port is provided for additional accessories such as GPS accessory. Includes nsol telescope control software for basic control of your telescope via computer (with optional rs-232 cable) and is compatible with optional nexremote telescope control software, for advanced control of your telescope via computer.


Amazon.com Celestron’s computerized NexStar 130 SLT adds affordable "Go-To" technology to a compact Newtonian reflector telescope. By using mirrors instead of lenses, the Newtonian optics of the NexStar 130 SLT produce an image nearly five times brighter than the NexStar 60 SLT refractor telescope. The package includes everything except the batteries, and features easy no-tool setup, two good eyepieces, and even includes a student version of "The Sky" planetarium software.

The Newtonian design of the NexStar 130 SLT is optimized to produce bright images over a wide field of view. When I use an optional 32mm Plossl eyepiece, the famous Double Cluster in Perseus looks like a display of celestial fireworks with streamers of stars trailing across the 2 degree field of view. The standard equipment 25mm eyepiece magnifies the image about 26 times, with a wide field of view just right for viewing deep space objects like star clusters or the Orion Nebula.

Celestron NexStar 130
The included 9mm eyepiece (72x magnification) offers great views of the Lunar disk and globular star clusters like M13. And when I add a 2x Barlow lens to the 9mm eyepiece for a total magnification of 144x, I can easily see cloud bands on the planet Jupiter and pick up detail in Saturn’s rings.

The NexStar 130 SLT also features Celestron’s patented SkyAlign technology. With SkyAlign I don't need a star chart or a compass to align the telescope, I just enter the date and time then point the telescope at three bright stars. SkyAlign tells me the star names, and allows the telescope to find over 4,000 stars, planets, and galaxies by just pushing a button. The accurate tracking makes it easy to get high power views of the planets, and allowed me to take some great pictures using a Celestron NexImage webcam. I also like the "Two-Star align" and "Solar System align" modes because I can often get the NexStar system up and running while older scopes are still waiting for their alignment stars to appear in he twilight.

Reflector telescopes offer more light gathering power per dollar than any other design, but that value is balanced by the fact that the mirrors may need to be aligned or "collimated" occasionally. Using Celestron’s Collimation Eyepiece

Celestron NexStar 130
I had no trouble fine tuning the optical alignment, and I was rewarded with sharp views of Lunar craters even when I pushed the magnification up to the theoretical limit of 300x. The other drawback of a computerized telescope, of course, is battery consumption. An optional PowerTank battery is a handy way to power the NexStar 130 SLT, and I like to keep the tripod legs short and observe while seated because this gives me a solid and comfortable view. --Jeff Phillips

Style Name: 130 SLT Newtonian Verified Purchase
OK, here is the Bible according to Celestron SLT scopes.

When the scope is working, it's fantastic (see below if you have a non-working scope with a boot loader failure). The Newtonian design is comfortable to look through - the eyepiece is at the front of the scope, and it is positioned around eye-level when standing. Newtonian optics are also simple, which keeps the cost down (and minimizes light lost to lens absorption).

The optic properties of this scope are outstanding. The 650mm focal length and 150mm (about 5-1/8") aperture are great specs, especially when paired with the highly-recommended Celestron accessory kit (Celestron Model 94303, available on Amazon). The scope comes with a 9mm and 25mm eyepiece, for magnifications of 72 and 26 power (magnification is focal length divided by eyepiece length, so magnification increases as focal length increases, and decreases as eyepiece length increases). The big 130mm aperture of this scope gives the scope a maximum useful magnification of about 307 power, using the rule of thumb that you can magnify 60 times for each inch of aperture.

At a focal ratio of f5, this is a fairly "fast" scope, meaning it lets in a lot of light for it's focal length. The f-number is the focal length divided by the aperture size, and the lower the f-number, the faster the scope. Faster is (generally) better. F-numbers will be familiar to photographers, and telescopic "lenses" operate on the exact same concept as fast photographic lenses. In photography, a lens is "fast" because it allows a shorter shutter speed (because it lets in more light), meaning you can capture faster motion that would be blurry with a longer exposure (as would be required by a "slower" lens).

I got my Celestron 130 SLT last month and am extremely happy with it. For the price, it's a great scope and the goto software was pretty easy to get the hang of. The sky mapping software that comes with the scope is also a great help and easy to use. A few caveats: Buy the AC power cord....otherwise you'll need new batteries every night. You'll need to reset the date/time on the goto computer every night.....it doesn't remember date/time between uses. It takes a few tries to get proficient with the three star align....it works pretty well, but you need to make sure you've setup your location and the date/time correctly. This scope isn't weighted and is very light. This causes it to shake a LOT when you touch it (i.e. when you're focusing). It takes a few seconds for it to stabilize after any adjustment. Some people weight the tripod tray to add stability. The focuser could have a finer adjustment. It takes a very steady hand to get optimal focus. The scope doesn't come with a Barlow lens, which is a necessity for this scope. You'll want to get one right away. The scope does have a 2" eyepiece adapter, which is unusual and a really nice feature on a starter scope such as this. It's worth buying a 2" eyepiece for wide views. I didn't find the NexStar PC driver software very useful (after buying the $15 cable to use it). Instead, I downloaded a trial version of the pricey NexRemote software, which allowed me to operate the scope from my laptop much more easily. These caveats are all very minor, as this is a solid scope with better optics and software than the alternatives. In short, the scope was way better than cheap toy scopes I'd used and all reviews I read said it had great optics for the price with very few problems/annoyances.Read more ›

Style Name: 127 SLT Maksutov Verified Purchase
November, 2012: After owning this product for 18 months, I am downgrading it.

The optics of this scope are pretty good. And the idea of an alt-az tracking mount with go-to features is sound. But the kit as actually delivered is problematic. If my experience is any indication, about half of the time, the kit will be out of commission due to failure of critical components.

As I noted in my original review, the Finderscope failed shortly after I got the kit, making the scope extremely difficult to aim and steer, and impossible to align for purposes of the tracking feature.

Since then, the Altitude motor has failed twice, and the plastic bracing of the tripod split clear through--fortunately NOT while it was holding the scope tube. Each of these situations has meant 2-1/2 months of the kit being out of commission while I begged Celestron for a return materials authorization number, shipped the materials to Celestron, waited for Celestron to check the parts in, and then waited 6 weeks for them to service or repair the parts.

The root cause is apparently low-quality materials, including cheap Chinese motors.

Celestron sells the SLT mount, hand-controller, and tripod as a kit without any optics for about $350. I recommend steering clear of that kit and any kit containing a tripod or mount made by Celestron, including their much-ballyhooed self-aligning SkyProdigy mounts, which, in their photos, appear to be made from the same underlying components.

At this point I am more seriously looking at products from Orion and Meade to replace the unreliable components from Celestron.
