Best Computerized GoTo Telescopes 2020 (TOP 9 Reviews)

Nowadays, many beginning astronomers like to choose a computerized instrument as their first telescope. Computerized telescopes offer many advantages, including requiring less (but contrary to popular belief, not zero) knowledge about the night sky to find objects, hands-free automatic tracking, and the ability to move the telescope with a button which induces less vibrations than manual pushing.

Why do we recommend Manual over GoTo?

Computerized telescopes are not for everyone. They require constant power, usually a 12-volt portable power supply (basically a car battery) or lithium-ion battery packs. You usually can’t move them at all manually without ruining the alignment – we’ll get back to this later.

Furthermore, GoTo is not exceptionally modern technology, having been around for three and a half decades now. Your typical computerized telescope has an interface basically the same as it had 20 years ago, with a small hand controller with the processing abilities of a pocket calculator, a small LCD screen with calculator-like text, and many functional limitations. Most computerized scopes have no internal clocks, and require re-alignment if power is lost even briefly.

Alignment of most, or even the best computerized GoTo scopes requires a two-star alignment – advertised features that supposedly let you align on any three objects or pointing the scope north and leveling it almost never work accurately – meaning you need to have a basic understanding of the motions of the sky and some bright stars to find in it. And there are occasionally failures and weird behavior requiring perhaps hours of troubleshooting–hours which could be spent at the eyepiece instead.

Star charts and observing books like Turn Left At Orion are much more interesting and engaging to read than the user manual of a Go-To telescope, and learning star hops in online forums is more interesting and engaging than consulting troubleshooting forums.

And it indeed is more fun to manually point a telescope, following star-hops to figure out where an object is in the sky. It’s more fun because it’s more engaging, and it gives you something to do. By learning to find objects, you’re learning the night sky. You’re learning to navigate it, to go from place to place, to learn which objects are in the neighborhood.

A few cases where I can see the need for Go-To scopes: Observatories and Star Parties, where you need to reliably find an object to show it off on schedule, and specific astronomical events like occultations, transits, and eclipses, where you need the tracking to keep you pointed at some obscure object so you don’t miss anything. And of course, astrophotography. But in all of these use cases, they’re not strongly overlapping with the interests of the beginner astronomer.

This all being said, the pros may outweigh the cons for you depending on your situation, and there’s absolutely no shame in owning a computerized instrument. So let’s get into our top picks for computerized telescopes.

Celestron NexStar 90SLT - Lowest price, choice under $400

The Celestron NexStar 90SLT is a 90mm f/14 Maksutov – the same optical tube as Celestron’s C90, designed to emulate the famed Questar 3.5 and the Meade ETX-90, the latter of which it is quite superior to mechanically. It is very good optically.

Due to the NexStar 90SLT’’s small aperture and long focal length, you’re not going to be viewing much in the way of deep-sky objects – the brightest nebulae and open star clusters won’t fit in the field, and the scope is too small to view most planetary nebulae, globular clusters and galaxies in detail. However, the setup is very portable, and this telescope doesn’t need collimation, so it’s at least worth consideration.

The 90SLT includes two Kellner eyepieces: A 25mm (50x) and 9mm (139x). Both are high enough in quality to get you started and work very well thanks to the scope’s super-long focal ratio, but you may want to upgrade later on to some Plossls or quality wide-field eyepieces.

The SLT (Star Locating Telescope) mount is designed to be very lightweight and inexpensive, but it’s so lightweight that it’s easily bumped or knocked over. However, it carries the 90SLT optical tube fine and has no issues with vibrations.

All in all a decent choice, but with limitations.

Celestron NexStar 90SLT

Celestron NexStar 130SLT - Choice between $450-$600

Riding the same mount as its close cousin the Celestron NexStar 90SLT, the NexStar 130SLT is a surprisingly affordable and cost-effective computerized instrument, and the 130mm aperture can actually show you stuff.

The 130SLT not only boasts 130mm (5.1”) of aperture at a fast focal ratio of f/5, but it also comes with a 2” focuser. This focuser allows you to use 2” eyepieces (sold separately) which can bring the scope’s field of view up to nearly 4 degrees – that’s 8 times the width of the full Moon! A wide-field telescope like the 130SLT is great for deep-sky observing.

However, there are some compromises. First, the inexpensive rack-and-pinion focuser means it’s hard to focus at high power. Second, the scope’s f/5 focal ratio means it suffers from coma at the edge of the field of view (particularly with wide-field 2” eyepieces) and inexpensive eyepieces such as the included 25mm and 9mm Kellners (26x and 72x) will not perform well even near the center of the field. So when buying the 130SLT, save some money for a few medium to high-quality eyepieces – you won’t regret it. The 130SLT also requires frequent collimation, another thing to be aware of. While annoying, collimation is nothing to fear and can be done in minutes with or without collimation tools.

The biggest problem with the 130SLT is the mounting – the light weight means it struggles to carry the 130mm optical tube effectively, resulting in some shakiness at high magnifications.

Celestron NexStar 130SLT


Celestron NexStar 5SE - Choice between $600-$750

The Celestron NexStar 5SE (“Special Edition”) is a Schmidt-Cassegrain with heritage going back to the original Celestron C5 introduced in the early 1970s.

The 5SE boasts a full 5” of aperture with StarBright multi-coatings and water-white corrector lens glass for maximum light gathering capability. However, being an f/10 Schmidt-Cassegrain means its field is rather narrow. You can’t use a standard f/6.3 reducer or 2” diagonal and eyepieces to increase the field of view like larger Schmidt-Cassegrains, as the 5SE’s baffle tube will vignette too much for either to work effectively. Also, the 5SE’s rather large secondary mirror – covering 37.8% of the scope’s diameter – reduces contrast quite a bit and has a slight impact on light-gathering ability, but the scope’s other features make up for this flaw for the most part.

Being a Schmidt-Cassegrain, the 5SE seldom needs collimation. However, when it does have to happen, collimation is a somewhat tedious affair requiring pointing the scope at a defocused star and adjusting the secondary mirror with an Allen wrench.

The 5SE mount is very sturdy, and can be upgraded with GPS, Wi-Fi control, and other capabilities later on. It also has quality gears. However, the built-in wedge is a useless gimmick and cannot be used accurately enough for any good equatorial tracking. The 5SE’s hand controller has a larger catalog of deep-sky objects than the SLT telescopes, but the interface is otherwise identical.

The 5SE and other SE telescopes include only one eyepiece – a 25mm Plossl, in this case yielding 50x. Set aside some money for at least one or two extra eyepieces for medium and high magnifications.

All in all, a pretty good choice.

Celestron NexStar 5SE


Celestron NexStar 6SE - Choice between $750-$800

The Celestron NexStar 6SE is even better than its smaller sibling. Along with a slightly larger steady, well-built mount and the same water-white corrector glass, XLT coatings, and accessory capability, the 6SE boasts an extra inch of aperture, a smaller secondary mirror, and the ability to use 2” accessories or an f/6.3 focal reducer without any vignetting, enabling a wider field of view.

The 6” Schmidt-Cassegrain optical tube, also known as the C6 is a comparatively new entry by Celestron – the C8 stretches back to the early 1970s and a prototype existed in the 1960s; the C90, C5, and C14 debuted in the mid-70s; the C11 debuted in the 1980s, and the C9.25 made its appearance in the 1990s. The C6 has only been around since 2006 when Celestron got bought by Synta, the same Chinese company that owns the Sky-Watcher brand.

The C6 tends to be quite good optically, and the 6” of aperture allows you to start doing some deep-sky observing beyond the brighter Messier objects and a few others. You won’t be nearly as tempted to upgrade as with a smaller instrument, which alone might justify the extra investment in the NexStar 6SE.

Like the 5SE, the 6SE is tedious to collimate, but thankfully it hardly needs it. However, you should make it a good habit to check during every observing session, as bad collimation will cause you to get fuzzy images and elongated stars at the eyepiece.

Overall, a very good choice for the beginner or experienced astronomer.

Celestron NexStar 6SE


Sky-Watcher GoTo Collapsible 8” Dobsonian - Choice Between $800-$1100

The Sky-Watcher GoTo Collapsible 8” is probably my favorite on this list, probably because it’s a Dob of course.

GoTo Dobsonians are different from tripod-mounted GoTo telescopes because they can always be pushed manually without ruining the alignment. This allows you to save power by nudging the scope to the approximate area of sky you’d like to observe, then using the GoTo to fine tune until you’re on target. You can move the scope manually during alignment if you want. And if you don’t feel like setting up the GoTo or forgot your battery, you can still observe with no problems.

8” of aperture is enough to start showing you a lot of interesting things previously impossible with a smaller instrument: Hundreds and hundreds of galaxies, resolution in a dozen or two globular clusters, and planetary nebulae littering the sky. Neptune’s moon Triton is relatively easy to see (it’s near-impossible with a 6”) and you may even be able to hunt for Uranus’ moons.

The 8” Collapsible comes with two Plossl eyepieces: A 25mm (48x) and 10mm (120x) which work just fine at the scope’s f/6 focal ratio, though you may want to upgrade later on to get some 2” wide-field eyepieces and 1.25” planetary eyepieces.

The only downsides? For one, the telescope can’t be broken down into small pieces, and even removing the optical tube from the mount can be a bit of a pain. Also, the open tube design means the scope requires a shroud.

Celestron NexStar 8SE - Choice Between $1100-$1300

The Celestron NexStar 8SE again has the same features of the NexStar 6SE, but boasting even larger aperture.

Unlike the aforementioned Sky-Watcher 8” Collapsible, the 8SE will fit in a very small space and doesn’t need any sort of shroud (though a dew shield helps). Like the NexStar 6SE, the 8SE can fit a reducer, T-adapter, or 2” diagonal on the back and the mount can be upgraded to have Wi-Fi, GPS or even self-alignment capabilities.

The only downsides: You still get the same single 25mm eyepiece, the field of view is starting to get uncomfortably narrow (particularly without a reducer or 2” eyepieces), and the 8” optical tube is a bit much for the mount to carry.

All in all, a good choice if you can’t fit an 8” Dob in your life, but with drawbacks compared to one.

Celestron NexStar 8SE


Orion XT10G - Choice Between $1300-$1500

The Orion XT10G is the largest telescope on this list. Providing a whopping 10” of aperture at only a slightly higher price than the NexStar 8SE, it is probably best for a user who plans on observing mostly at home.

Like the Sky-Watcher 8” Collapsible, the XT10G can be moved manually even if the GoTo system is in operation, as well as aligned manually. You can also use the entire scope without power or GoTo if you would like to.

The XT10G is also the heaviest and bulkiest telescope on this list, however. It will fit in an SUV, but the 48” long tube and large base mean it’s not well-suited for smaller cars. The XT10G is really ideal if you don’t plan on transporting it too often – or just have a big car or truck.

The XT10G has a focal ratio of f/4.7. This means that you’ll need quality wide-angle eyepieces to get the sharpest low-power views, and ideally a coma corrector as well. Collimation is also harder than with a longer/slower instrument, though still plenty easy for the beginner. Focusing with a fast telescope like the XT10G is tricky, especially at high power, but thankfully Orion has solved that issue by including a high-quality dual-speed Crayford focuser with the XT10G.

The included 28mm DeepView eyepiece (43x) would be nice with a Schmidt-Cassegrain or long refractor or even an f/6 Dobsonian, but it’s pretty disastrous at f/4.7 with the XT10. Not only is the field of view kind of narrow, but the simple Kellner optical design means the edge of the field of view not only suffers from coma but astigmatism as well. The 12.5mm crosshair Plossl is relatively nice but the crosshairs are permanent so it’s really only good for aligning the scope, a task for which a crosshair eyepiece is kind of overkill.

Overall, a good scope if you don’t mind the bulk and can upgrade the accessories.

Orion XT10G

Celestron NexStar Evolution 8” - Choice Between $1500-$1900

Celestron really took the “Evolution” name literally when they made the NexStar Evolution 8. The Evolution 8 still has the same optical tube and hand controller as the NexStar 8SE, but with a number of upgrades.

Firstly, the scope has a much sturdier tripod, eliminating the stability issues of the 8SE. Second, the mount has a built-in lithium ion battery, which eliminates the issues of having to buy a power supply as well as cord wrap.

The Evolution’s main selling point is that it can be controlled remotely via a phone or tablet. This is rather unnecessary, especially since a hand controller is still provided, but can be a nice feature, particularly for kids.

The Evolution 8 comes with two Plossl eyepieces: A 40mm (50x) and 13mm (153x) of reasonably high quality. However, you’ll want to get a focal reducer or 2” diagonal and eyepieces to maximize the field of view you can get with the scope, as well as one or two additional high-power eyepieces.

Overall, an excellent choice.

Celestron NexStar Evolution 8”


Celestron NexStar Evolution 9.25” - Choice Above $1900

The NexStar Evolution 9.25” is, as the name says, a scaled-up version of the Evolution 8. Care has been taken by Celestron to make this scope just as user-friendly, so the tripod has been scaled up as well to a heavier-duty version with thicker legs for maximum stability.

The 9.25” optical tube has a slightly different optical configuration than Celestron’s other Schmidt-Cassegrain telescopes. This results in it being easier to collimate and having sharper images. However, the 2350mm focal length of the C9.25 tube results in a field of view that feels rather claustrophobic even with 2” low-power eyepieces, and thus it’s best for viewing the Moon, planets, and small deep-sky objects such as globular clusters and planetary nebulae.

A great choice if you don’t mind the narrow field and high price.

Celestron NexStar Evolution 9.25”

Honarable Mentions

1. Celestron AstroFi 130

This scope is identical to the Celestron NexStar 130SLT, but it lacks a hand controller and you instead have to use your phone or tablet to operate it wirelessly. There have been enough complaints about this technology that I hesitate to recommend it, but feel free to take a bit of a gamble and try it if the lower cost and/or remote control appeals to you.

2. Meade 6” ACF LX65

A relative newcomer to the market, the 6” LX65 has Meade’s signature Advanced Coma Free optics and UHTC coatings. The ACF optics are a nice feature – the edge of the field is sharper than a regular SCT’s. The UHTC coatings are basically the same as Celestron’s StarBright XLT coatings and are little more than a brand name for the same product.

Uniquely among mounts, Meade has included a dual dovetail saddle to allow you to attach another telescope to the mount. However, the mount’s capacity is probably not as high as Meade claims and I see little point in trying this, anyway. The mount also has a nice built-in handle.

The LX65 tube and mount are much beefier and contain less plastic than the NexStar 6SE, and the Meade Autostar hand controller has some features the NexStar+ controller lacks.

The included eyepiece is really cheap, and the scope is really heavy, however, so it’s not my favorite.

3. Meade 8” ACF LX65

Most of my comments about the 6” LX65 apply here, except that in addition the setup overall isn’t the sturdiest. However, the 8” ACF LX65 is closer in price to its Celestron counterpart, which also has stability concerns.

4. Orion XT8G

This scope costs more than the Sky-Watcher 8” Collapsible, and lacks the collapsing tube feature. The only discernible upgrade is in the focuser and eyepieces, and the price difference between the XT8G and the 8” Collapsible is greater than the price of the focuser and eyepieces, so I don’t see any good reason to choose the XT8G unless you MUST have a solid tube or can’t obtain the 8” Collapsible.

5. Celestron NexStar Evolution 6

All of my comments about the NexStar Evolution 8 apply here, except that the Evolution 6 of course uses a 6” optical tube. However, for the same price, there are larger telescopes available. But if you like the other features the Evolution has to offer and can’t afford the 8” model, consider this one.

6. Orion XT12G

All of my comments about the XT10G apply here, except that this scope is even heavier, longer, and harder to transport. Even someone relatively physically strong will have trouble moving the wide, heavy optical tube and super-heavy particle board base. The accessories are still pretty horrendous, too.

Tips on Choosing the Best Computerized Telescope

  • Power

Except for the Celestron NexStar Evolution telescopes, almost every computerized telescope requires a portable power supply, either a 12-volt lead-acid rechargeable DC battery or lithium-ion rechargeable batteries. Either adds cost to your scope and has to be hauled around. Some telescopes can use AA batteries as backup, but will quickly guzzle them within a few observing sessions and continually replenishing them is expensive. So always budget at least $50 for a power supply.

  • You Get What You Pay For

Cheaper computerized telescopes have weaker tripods, plastic or imprecise gears, and tend to consume more power. They’re also typically smaller and include lower-quality or fewer accessories.

  • Aperture

More aperture means more light-collecting area which allows you to see fainter objects more easily. Light-gathering ability goes up with the square of the aperture, so an 8” telescope gathers 4 times as much light as a 4” telescope.

Aperture also increases resolution, which in turn increases the maximum magnification usable with a given telescope. Resolution increases linearly with diameter, so an 8” telescope has twice the resolution of a 4” telescope.

  • Magnification

On a night of good seeing, a telescope can be used at as much as 40-50x per inch of aperture. However, more power doesn’t show you more things and most planetary/lunar observers use around 30x/inch for observations. For deep-sky observing, particularly for large objects and to find things in the sky, use as low a power as possible.

2 thoughts on “Best Computerized GoTo Telescopes 2020 (TOP 9 Reviews)”

  1. I own an old nexstar 4 . The hand control failed although the direction buttons still work. I have a large tripod, a full set of eyepieces and filters, and a sun filter. What can I purchase that would be reliable and utilize some of my old accessories. I would want to have minimal alignment or setup requirements.

  2. Thank you for this site. My brother and his family are going to moving into a new home in a secluded area where they should be surrounded by beautiful dark skies and nature, and I want to gift them a telescope as a housewarming. Honestly, I do not feel we have any future astronomers among the group, but I would like to give them something sturdy and amateur user friendly. I like the idea of giving them a “push to” or “go-to” telescope. I was looking at the Meade StarNavigator NG based on the Space.com site, but I see it is not a recommendation for you. Can you help me determine what I should be looking at given what I have shared, please? Thank you for your consideration
