    •  Computerized hand control with 4,000-object database SkyAlign allows you to align on any 3 bright celestial objects Motorized Altazimuth mount Focal ratio: f5 Focal length: 650mmEditorial ReviewsAmazon.comAmazon.com Celestron’s computerized NexStar 130 SLT adds affordable "Go-To" technologyto a compact Newtonian reflector telescope. By using mirrors instead of lenses, the Newtonianoptics of the NexStar 130 SLT produce an image nearly five times brighter than the NexStar 60SLT refractor telescope. The package includes everything except the batteries, and features easyno-tool setup, two good eyepieces, and even includes a student version of "The Sky" planetariumsoftware.The Newtonian design of the NexStar 130 SLT is optimized to produce bright images over awide field of view. When I use an optional 32mm Plossl eyepiece, the famous Double Cluster inPerseus looks like a display of celestial fireworks with streamers of stars trailing across the 2degree field of view. The standard equipment 25mm eyepiece magnifies the image about 26times, with a wide field of view just right for viewing deep space objects like star clusters or theOrion Nebula.The included 9mm eyepiece (72x magnification) offers great views of the Lunar disk andglobular star clusters like M13. And when I add a 2x Barlow lens to the 9mm eyepiece for a totalmagnification of 144x, I can easily see cloud bands on the planet Jupiter and pick up detail inSaturn’s rings.The NexStar 130 SLT also features Celestron’s patented SkyAlign technology. With SkyAlign Idont need a star chart or a compass to align the telescope, I just enter the date and time thenpoint the telescope at three bright stars. SkyAlign tells me the star names, and allows thetelescope to find over 4,000 stars, planets, and galaxies by just pushing a button. The accuratetracking 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 "SolarSystem align" modes because I can often get the NexStar system up and running while olderscopes 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 thatvalue is balanced by the fact that the mirrors may need to be aligned or "collimated"occasionally. Using Celestron’s Collimation EyepieceI had no trouble fine tuning the optical alignment, and I was rewarded with sharp views of Lunarcraters even when I pushed the magnification up to the theoretical limit of 300x. The otherdrawback of a computerized telescope, of course, is battery consumption. An optionalPowerTank battery is a handy way to power the NexStar 130 SLT, and I like to keep the tripodlegs short and observe while seated because this gives me a solid and comfortable view. --JeffPhillipsPros: Wide field views Computerized go-to tracking Light and portableCons: Short battery life Sensitive to vibrationSuggested Options: Celestron Accessory Kit Celestron PowerTank battery Celestron Collimation Eyepiece

    • The popularity of our NexStar 114 models inspired us to go bigger! We are proud to introduceNexStar 130 SLT. The NexStar 130 SLT has 30% more light-gathering power than our 114mmtelescope.And the 130 SLT, like the other models in the SLT Series, comes with a fully computerized handcontrol. The computerized hand control gives you the ability to automatically slew to any of its4,000+ objects, including over 600 galaxies, 300 clusters and dozens of beautiful binary stars.With its pre-assembled, adjustable steel tripod, the NexStar 114 SLT can be up and ready to usein a matter of minutes. Our new SkyAlign alignment technology and the included StarPointerFinderscope 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 cloudbelts on Jupiter or a number of the Messier objects such as the globular cluster in Hercules(M13), or the Great Nebula in Orion (M42). Begin to explore some of the fainter Messier objectsusing the additional light-gathering capabilities of the 130 SLTs 5" primary mirror.Because of the Newtonian design, the mirror gives fully color-corrected views that are bestsuited for astronomical use.Specs Optical Design: Reflector GPS: Optional CN-16 GPS Accessory Weight: 18 lb (8.16 kg) Aperture: 130 mm (5.12 in) Focal Length: 650 mm (25.59 in) Focal Ratio: 5 Finderscope: StarPointer Mount: Motorized Altazimuth Eyepiece 1: 25 mm (0.98 in) Magnification 1: 26 x Eyepiece 2: 9 mm (0.35 in) Magnification 2: 72 x Accessory Tray: No Tool, Quick release Tripod: Steel CD ROM: "The Sky" Level 1 and NexStar Observers List (v2.6.4c) Highest Useful Magnification: 307 x Limiting Stellar Magnitude: 13.1 Resolution (Rayleigh): 1.07 arcsec Resolution (Dawes): 0.89 arcsec Photographic Resolution: 400 line/mm Light Gathering Power: 345 x Angular Field of View: 1.7 ° Linear Field of View (@1000 yds): 91 ft (27.74 m) Optical Coatings: Aluminum Secondary Mirror Obstruction: 1.7 in (43.18 mm)

    • Most helpful customer reviews114 of 116 people found the following review helpful.Great ScopeBy Maritime ResearchI got my Celestron 130 SLT last month and am extremely happy with it. For the price, its a greatscope and the goto software was pretty easy to get the hang of. The sky mapping software thatcomes with the scope is also a great help and easy to use. A few caveats: Buy the AC powercord....otherwise youll need new batteries every night. Youll need to reset the date/time on thegoto computer every night.....it doesnt remember date/time between uses. It takes a few tries toget proficient with the three star align....it works pretty well, but you need to make sure youvesetup your location and the date/time correctly. This scope isnt weighted and is very light. Thiscauses it to shake a LOT when you touch it (i.e. when youre focusing). It takes a few seconds forit to stabilize after any adjustment. Some people weight the tripod tray to add stability. Thefocuser could have a finer adjustment. It takes a very steady hand to get optimal focus. The scopedoesnt come with a Barlow lens, which is a necessity for this scope. Youll want to get one rightaway. The scope does have a 2" eyepiece adapter, which is unusual and a really nice feature on astarter scope such as this. Its worth buying a 2" eyepiece for wide views. I didnt find theNexStar PC driver software very useful (after buying the $15 cable to use it). Instead, Idownloaded a trial version of the pricey NexRemote software, which allowed me to operate thescope from my laptop much more easily. These caveats are all very minor, as this is a solid scopewith better optics and software than the alternatives. In short, the scope was way better thancheap toy scopes Id used and all reviews I read said it had great optics for the price with veryfew problems/annoyances. I got a great view of Jupiter and its moons the first night I used it.After I got the hang of it, I started checking out Messier Objects, including the brighter galaxiesand nebulae, which are easily recognizable with this scope. Im extremely pleased with it and Imvery glad I got this scope instead of comparable competing scopes, which all seem to haveserious issues per the various reviews Ive read.65 of 70 people found the following review helpful.This scope needs maintenance.By Tom H.I received this telescope about a month ago. It is easy to use and works well. The 2 lenses thatcome with the scope allow you to begin checking things out in the sky, but there are a few morethings needed. 1- A filter kit (at least one filter for the moon. Its too bright to look at withoutone). 2- 2X Barlow Lens. This will double the magnification of the lenses you have.Also, this scope needs maintenance. The mirrors must be perfectly collimated (lined-up) on anF5 scope. (The lower the focal ratio, the more precise the collimation must be, and F5 is low.)My scope needed collimating right out of the box. The scope does not have to be shaken hard toknock the mirrors off of angle or alignment. This requires tools and some mechanical ability. Getinfo online or visit local stores that sell reflector scopes. I paid $200 for my set of collimatingtools (Sight Tube, Cheshire and Autocollimator). For this scope to work properly, thismaintenance must be done regularly.PS- This scope is a Newtonian Reflector type.
    • 23 of 23 people found the following review helpful.Great optics. Heres what to do if you get the "BOOT LOADER Invalid Pkg: 0080"error.By David C. FilmerOK, here is the Bible according to Celestron SLT scopes.When the scope is working, its fantastic (see below if you have a non-working scope with a bootloader failure). The Newtonian design is comfortable to look through - the eyepiece is at thefront of the scope, and it is positioned around eye-level when standing. Newtonian optics are alsosimple, 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 Celestronaccessory kit (Celestron Model 94303, available on Amazon). The scope comes with a 9mm and25mm eyepiece, for magnifications of 72 and 26 power (magnification is focal length divided byeyepiece length, so magnification increases as focal length increases, and decreases as eyepiecelength increases). The big 130mm aperture of this scope gives the scope a maximum usefulmagnification of about 307 power, using the rule of thumb that you can magnify 60 times foreach inch of aperture.At a focal ratio of f5, this is a fairly "fast" scope, meaning it lets in a lot of light for its focallength. 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, andtelescopic "lenses" operate on the exact same concept as fast photographic lenses. Inphotography, a lens is "fast" because it allows a shorter shutter speed (because it lets in morelight), meaning you can capture faster motion that would be blurry with a longer exposure (aswould be required by a "slower" lens).The auto-orientation works like magic, but its better to give it very precise time and location.Use a GPS for location; dont just tell it what city you are in (you can choose your location inputmethod). For some reason, the controller can remember your last location and the time zone ofyour previous observation, but the controller does not keep time when it is switched off, so youmust enter the (exact) time again whenever you switch the power off and back on (Cmon,Celestron - seriously?)You can orient the scope by pointing the scope at ANY three bright objects (you do not need toknow what they are) or two objects if you know what they are (but this is said to be less precise).The scope must be level (it has a built-in level bubble). Although this scope is not reallyclassified as a "beginners scope," it is great for beginners - you dont need to know anything tobegin viewing amazing things, and a beginner will not "outgrow" this scope anytime soon. Theonly comparable computerized Newtonian scope that I could find in this price range is the OrionStarBlast 6i IntelliScope, but it is available only with a table-top mount (???). If that Orion scope(750mm focal length, 6-inch aperture) was available with a sturdy tripod mount in this pricerange then I would be writing this review for that scope, because I would have bought that scopeinstead, without a doubt. Orion lost my business because they expected me to have a studyTABLE available at each observation site.
    • The optional Celestron accessory kit includes (among other things) 6mm, 8mm, 13mm, 17mm,and 32mm eyepieces and a Barlow 2X adapter. With a 6mm eyepiece and a Barlow 2X adapter(which effectively doubles the magnification of the eyepiece, making it a 3mm focal length), thescope can achieve a magnification of 216 power (pretty respectable). You could purchase shortereyepieces or a 3X Barlow to push the magnification near the 307 power limit, but I dont thinkyou will find yourself wanting to do so - you will be amazed at what you can clearly see (thebands of Jupiter and its Galelian moons, the rings of Saturn, etc). Note that the 307-power limitcannot be exceeded with eyepieces or Barlow lenses - the image will be pretty much worthless ifyou try to exceed this limit, which is a function of how much light the scope can gather (which isdetermined by the aperture size). As you approach this limit, the image quality decreases, so youwill probably find images much more satisfying at low-to-mid-200 power than you would attheoretical maximum 300+ power.The gray moon filter in the accessory kit is especially useful for bright objects (such as the moon,of course, but also Venus and Jupiter).The longer eyepieces are needed for viewing large objects such as various asterisms, galaxies,and nebula. Some of these objects span 2 or 3 degrees of sky (or more) - which is really big (thesun and moon are 0.5 degrees.) Some objects can only be fully viewed at very low magnification(such as afforded by binoculars), so dont make the mistake of assuming that high magnificationis always better. If you attend a star party, expect to find binoculars (usually mounted on atripod) in use. The Pleiades star cluster, for example, is best observed at lower magnification.The eyepieces that come with the scope (and the accessory kit) are 1.25" diameter, but the scopecan also accept large, very nice (and expensive) 2" eyepieces - just remove the 1.25" adapterwhich comes with the scope.The tripod mount is good, but will wiggle a bit in the breeze, especially at higher magnifications.It helps to add some weight - the tripod has a small shelf which lends itself to this purpose. Acouple bags of rice or beans will do, but I bought a 20-lb theatrical-grade sandbag (doublezippers keep sand out of my optics, and sand doesnt attract bugs or rodents). Put that weight onyour tripod and dont touch the scope while viewing (take your hand OFF of the focus knob) andyou should have a steady view, even in breezy conditions. Stiff winds may require additionalmeasures, such as springs attached to the legs and anchored to stakes in the ground.I was told by someone at a Star Party that this mount is not well suited for long-exposure deep-field photography. As it tracks objects across the sky, the mount makes slow adjustments, but itdoes not adjust azimuth (side-to-side) and altitude (up-and-down) at the same time, but insuccession, in a stair-step pattern. The eye wont notice, but a long-exposure photo will seeblurring. Alas. But I have not verified this info. In any event, it should work fine for short-exposure shots, like the moon (you will need a camera adapter, of course).The motorized mount goes through batteries pretty fast, especially if it is tracking something allthe time. The default power source of eight (standard alkaline) AA batteries will probably last anight, but I would not push it to two nights if I had been tracking the whole night before. You
    • can hook it up to a car battery and it will run forever. I use a wheelchair gel battery - they aresmaller and lighter than car batteries, and will take the deep-cycle use (charge and deplete,charge and deplete). Buy a trickle charger and use it when the battery is not being used, to keepthe battery fresh and extend its life. Or you can get the Celestron Power Tank. You can use anAC adapter if you have access to AC - any adapter that puts out 12 volts DC at 2.5 amps or morewith a 2.5mm barrel plug (negative on outside, which is standard) will work just fine (you canhave all the extra amps you want - it wont hurt anything). There are scads of suitable adapters onAmazon that are a whole lot cheaper than the one Celestron sells.This is a Newtonian scope, and Netownians are subject to collimation errors, meaning that thetwo mirrors are not precisely aligned. I recommend the Celestron Collimation Eyepiece(Celestron Model 94182, available on Amazon). This will allow you to quickly and easily (andaccurately) calibrate your scope for an absolutely perfect image. Some people do this each timethey transport their scope, because any sort of vibration can cause the mirrors to drift (though itseems to be a rather minor problem for this scope, in my experience). The instructions that comewith the eyepiece are excellent.Get a red flashlight. Celestron makes one that has a dimmer. Red wont mess up your nightvision nearly as badly as other wavelengths.I rate this scope at five stars, despite the BOOT LOADER problem (solution below).========= BOOT LOADER PROBLEM====================================================Within two days of getting this scope, it failed to "boot" (the mount is computerized, and it needsto successfully "boot up," just like any computer. If it cannot boot, it is useless). When the handcontroller was turned on, it said, "reading packages" and then stopped with an error message,"BOOT LOADER Invalid Pkg: 0080." This renders the scope dead - it cannot be moved, evenwith manual arrow buttons.Fixing the problem is a bit tricky. You need to flash the firmware in your hand controller (whichhas somehow become corrupted), but its not as simple (or as well-documented) as it should be.First, you need to buy a serial cable to connect your computer to the controller. Its 9-pin RS-232(female) on one end and a modular connector on the other end (it looks like a telephone plug).The Celestron model number for this cable is 93920, and you can buy it on Amazon.If you have a reasonably modern computer then you probably dont have a serial port. If youhave a 9-pin MALE D-connector then you have a serial port (though it may be disabled in yoursystem BIOS settings). Otherwise you need to buy serial capability - I recommend a USB toSerial converter (also available on Amazon from many suppliers).Connect the computer to the controller. Make sure you are plugging the serial cable into the baseof the handheld controller, and not into the body of the motorized mount. Both the controller andthe mount have modular serial connections (and both can be flashed), but you are flashing the
    • handheld controller, not the mount.You need to download and install the Celestron Firmware Manager (CFM) from Celestronswebsite (its in Support/Downloads/Software, near the bottom of the list). Its a Java application,so it should work on any computer platform. But it will be downloaded as a zipfile - you mustextract the contents and then run CFM.jar (on Windows, just double-click it). You cant run itwithin the zipfile - it must be extracted. Make sure your scope is connected first.THIS IS IMPORTANT: There are two types of Celestron motorized controllers. Theres theAlt/Az (which is used by this SLT mount, as well as LCM, SE 4/5/6/8, and CPC) and theEquatorial mount (used by CGE, Advanced, and CGE*). In the CFM menu (along the top of theCFM window), select "Hand Control" and make sure the proper type of control is selected foryour model of scope (this CST scope is Alt/Az). THIS IS THE REALLY REALLYIMPORTANT PART - Under the mount type selection you will see three radio buttons. The firstone is selected by default, and it tells CFM to automatically detect the mount type. This is NOTGOOD. CFM thought I had an Equatorial mount. Even if I select Alt/Az, my selection will beoverridden by the "Auto Detect" option. Select the Second option, which says "Always do what Iselected this time" and CFM will then respect your selection.Now flash the controller in the CFM, and you should be good to go.And if you go to a remote site or star party, its a good idea to bring a laptop with CFM (and yourcables), just in case you need to do this again. I was 160 miles from home (beneath a rare Class-1darksky!!!) when I had this problem. Fortunately it was only an hour before sunrise, so I didntmiss too much.See all 45 customer reviews...My Associates Store | Shopping Cart Browse by CategoryPatio Furniture SetsCamera & Photo Similar ItemsCelestron Vibration Suppression ...$39.39
