What really sets the NexStar 8SE apart at this price point is its computerized GoTo mount with a comprehensive hand controller that includes a database of over 40,000 celestial objects.
After a quick SkyAlign setup, the telescope can automatically locate and track targets across the sky, making it much easier to explore the night sky than with a fully manual scope. This means even beginners can start seeing impressive astronomical sights with minimal frustration, while more experienced observers appreciate the convenience and control the motorized tracking provides.
However, it’s worth noting that the 8SE isn’t perfect. Some users report that the single-fork arm mount can feel a bit wobbly at higher magnifications, especially if accessories are added or the tripod legs are fully extended, and additional eyepieces or power solutions may be needed to get the most out of the telescope. Collimation (optical alignment) and astrophotography on this mount also have a learning curve compared with dedicated imaging rigs.
Still, for many astronomy enthusiasts, the NexStar 8SE strikes an excellent balance of optical performance, automation, and price, making it a standout choice for backyard stargazing and introductory astrophotography under $2,000.
2. Celestron StarSense Explorer 12-inch App-Enabled Telescope

- 12-INCH REFLECTOR WITH IMPRESSIVE VIEWS: The 305mm Newtonian reflector with high-reflectivity XLT coatings delivers sharp, vivid views of the Moon, planets like Jupiter and Saturn, and deep-sky favorites like the Orion Nebula and Andromeda Galaxy.
The Celestron StarSense Explorer 12″ Dobsonian combines classic Dobsonian optical power with modern smartphone-guided navigation, making deep-sky observing accessible even to newer astronomers.
Its 12-inch (305 mm) aperture Newtonian reflector gathers a tremendous amount of light, allowing bright, detailed views of the Moon, planets like Jupiter and Saturn, star clusters such as the Pleiades, and even fainter nebulae and galaxies that smaller telescopes struggle to reveal.
The optical tube’s fast f/4.9 focal ratio and XLT coatings help maximize contrast and brightness across a wide range of targets, giving users richly textured views that keep on impressing throughout the night.
Where this telescope truly stands out is with Celestron’s StarSense Explorer smartphone-app system, which uses your phone’s camera and patented plate-solving technology to determine exactly where the telescope is pointed in the sky. Rather than relying on manual star hopping or an expensive computerized GoTo mount, the app displays on-screen arrows and a targeting “bullseye” to guide you directly to thousands of celestial objects visible on any given night.
This makes finding deep-sky gems far easier — especially for beginners or casual observers who might otherwise be overwhelmed by star charts and manual searches — without ever sacrificing the hands-on feel of a classic Dobsonian.
That said, this telescope isn’t without its trade-offs. At its size and fast focal ratio, it’s quite large and heavy, meaning setup and transport take more effort than with smaller scopes, and the single included eyepiece often leaves many observers upgrading for the best views.
The StarSense app, while powerful, also depends on having a compatible smartphone and good sky visibility — it can struggle under heavy light pollution or near the horizon with faint targets — so it’s not a perfect substitute for learning the night sky itself.
Still, for its price and performance, the StarSense Explorer 12″ offers a compelling mix of serious light-gathering power and approachable technology, making it a standout choice for observers who want to grow into deep-sky astronomy without breaking the bank.

Serious Amateurs will Love the SW 100mm ED-APO Refractor Sky-Watcher high-performance ED-APO refractors offer premium optical performance for the discriminating amateur astronomer.
The Sky-Watcher Evostar 100ED uses a crown glass element, an ED glass element, and state-of-the-art optical multi coatings in its apochromatic ED doublet optics. The result is images that are essentially free of the annoying halo of unfocused violet light (chromatic aberration) that often mars the view of bright stars and solar system objects.
In addition, there is no loss in contrast such as you will find in reflector and catadioptric scopes that have a secondary or diagonal mirror hanging in the light path to scatter light..
The 100mm Sky-Watcher doublet optics are even more appealing when you consider that this Sky-Watcher apo is loaded with features other manufacturers charge extra for (or don’t even have available) – such as an 8 x 50mm right-angle finderscope, a 2″ dielectric star diagonal with 1.25″ and 2″ compression ring accessory holders, two 1.25″ LE (Long Eye Relief) eyepieces (LE20mm and LE5mm); and a foam-lined aluminum-clad carrying case.
A mounting cradle-ring clamps over OTA and allows the user to adjust the orientation and position of the scope relative to the mount to optimize viewing comfort and balance, while avoiding interference with other equipment. The scope is offered without a mount or tripod, but a Vixen-style dovetail plate makes it compatible with any alt-az or equatorial mount with a Vixen-style saddle.
The Sky-Watcher Evostar 100ED has enough premium high contrast/high resolution optical performance to let you use it as the heart of your observing system.
With a weight of 11.3 pounds, it will work well on most medium duty equatorial mounts, but may start to push the capacity of some altazimuth mounts. That said, the Sky-Watcher Evostar 100ED is still light enough to take out and set up for observing on very short notice.
Each air-to-glass surface in the Sky-Watcher PRO 100ED doublet objective lens has MHC (Metallic High-Transmission Coating) antireflection multi coatings on all air-to-glass surfaces for high light transmission, minimal light scatter, and excellent contrast.
Contrast-enhancing internal light baffles in the tube and focuser drawtube and a specially darkened tube interior provide dark sky backgrounds and high terrestrial contrast.
Considering its surprisingly low price for an apochromatic doublet, adding in the extra features you get at no extra cost, and in view of the great optical performance that comes as standard equipment, the 100mm Sky-Watcher Evostar 100ED is a terrific buy.
4. Sky-Watcher Flextube 250 SynScan 10″ Dobsonian
- LARGE APERTURE: Get a bright, bold viewing experience at a fraction of the cost of other optical designs.
- INNOVATIVE COLLAPSIBLE DESIGN: Unique strut design allows for optical tube to collapse for ease of portability while keeping collimation.

The Sky-Watcher Flextube 250 SynScan 10″ Dobsonian is a large-aperture Newtonian reflector with computerized GoTo functionality, combining classic Dobsonian light-gathering power with automated target finding.
With its 10-inch (≈257 mm) primary mirror and a fast f/4.7 focal ratio, this telescope can deliver bright, detailed views of the Moon, planets, star clusters, nebulae, and many galaxies — significantly outperforming smaller scopes in deep-sky performance thanks to the aperture size alone.
Its collapsible tube design makes transport and storage easier than traditional solid Dobsonians of similar size, while still providing the same optical performance once set up.
What sets this model apart from many other large Dobsonians under $2,000 is the SynScan GoTo system, which helps you automatically sleuth to thousands of celestial objects.
Powered by Sky-Watcher’s computerized hand controller and built-in encoders, the GoTo feature eliminates much of the manual star-hopping that beginners often find intimidating, letting you locate targets with a few button presses. With proper alignment, you can browse deep-sky treasures or planetary targets without spending a lot of time learning the night sky first — a big plus for observers who want results fast.
However, there are some trade-offs typical of 10″ Dobsonians and this design in particular. The telescope is quite heavy and bulky once assembled, so it’s not a true “grab-and-go” setup and works best from a fixed observing site rather than frequent travel.
Some users also report that the GoTo system isn’t as plug-and-play as smaller computerized mounts — requiring adjustments or even tweaks like adding counterweights or leveling aids to work optimally — and that the basic focuser and included eyepieces may eventually be upgraded for better high-power views.
Still, for observers who want serious aperture plus automated object locating in one package, the Flextube 250 SynScan offers a compelling combination of performance, convenience, and affordability under ~$2,000
5. Askar 80PHQ Telescope
- The overall finish of 80PHQ is evenly painted. The ivory and flawless coating of the main tube feels comfortably pimply, which can not only increase your grip, preventing the telescope from slipping off from your sweaty hands, but also improve its texture, avoiding the tedious monotony.
- 80PHQ inherits the optical design of the PHQ- family, adopting a 3+1 quadruplet lens structure which contains two pieces of ED glass that can effectively reduce chromatic aberration and enhance clarity and sharpness.
- It’s worth mentioning that all astrographs from PHQ- family come with an integrated lens combination rather than simply placing three major lenses and a corrector together in a line. In another word, the whole optical system cannot solely perform without any piece of these lenses. This structure design leads to a more rational lens arrangement, better vignette control and superior image quality.
- The focal ratio of 80PHQ is f/7.5. It’s a “long” focal-ratio astrograph compared with other counterparts from Askar. It’s a little bit longer even compared with 107PHQ which is f/7 in focal ratio.
- Like 107PHQ, you don't need to calculate the back focus distance within the connection limit. Besides, users don't need to add an extra 1× flattener due to its powerful flatfield optical design, which simplifies the operation.
The Askar 80PHQ Apo Quadruplet Telescope is a standout astrophotography-oriented refractor designed for enthusiasts who want excellent optical performance in a relatively compact and portable package.
Its 80 mm aperture with an f/7.5 focal ratio and quadruplet air-spaced APO design (including two ED glass elements) delivers sharp, high-contrast images across a flat field, making it ideal for capturing wide and moderate field deep-sky objects without needing a separate flattener lens. This built-in flat-field performance is a major advantage for imaging nebulae, star clusters, and galaxies with minimal field curvature — even on large APS-C or modest full-frame sensors.
Mechanically, the 80PHQ is thoughtfully built. It features a robust 3″ dual-speed rack-and-pinion focuser with 360° rotation, which gives precise control essential for both astrophotography and visual observing.
The telescope also comes with multiple photographic adapter threads and a dovetail plate with tube rings, making it easy to integrate with a variety of mounts and camera setups straight away. Users have praised the excellent build quality and smooth focuser action, noting that the optics produce tight, round stars even near the edge of the field, a quality often hard to find in telescopes at similar price points.
However, the 80PHQ is not without trade-offs. Its 80 mm aperture limits light-gathering compared to larger instruments, so deep-sky imaging of very faint targets will require longer exposures and a good tracking mount. Some astrophotographers also choose to use an optional reducer to make the focal ratio faster (e.g., f/5.7) for a wider field of view — though doing so adds to the total cost.
Despite this, for its class the Askar 80PHQ remains a versatile, high-quality telescope that excels in flat-field imaging and visual performance, making it a smart choice under ~$2,000 for observers who want to grow their skills without investing in a larger, heavier scope right away.

- 10-INCH REFLECTOR WITH IMPRESSIVE VIEWS: The 254mm Newtonian reflector with high-reflectivity XLT coatings delivers sharp, vivid views of the Moon, planets like Jupiter and Saturn, and deep-sky favorites like the Orion Nebula and Andromeda Galaxy.
The Celestron StarSense Explorer 10″ Dobsonian Telescope is a standout choice for astronomy enthusiasts who want big-aperture performance paired with intuitive app-assisted navigation — all without the cost and complexity of a motorized GoTo system. Its 10-inch (254 mm) primary mirror gathers a substantial amount of light, producing bright, detailed views of celestial objects including the Moon’s craters, the rings of Saturn, Jupiter’s cloud bands, and many deep-sky objects like nebulae and star clusters.
A large aperture like this gives significantly more light-gathering capability than smaller beginner scopes, making it a rewarding telescope for both newcomers and more experienced observers who want powerful performance in the backyard.
What really sets this model apart is Celestron’s StarSense Explorer smartphone-app integration. Instead of a computerized mount with motors that automatically slews the telescope, the StarSense system uses your phone’s camera and plate-solving technology to determine where the telescope is pointed and guides you with on-screen arrows and targets to find objects in the sky.
This push-to system makes locating deep-sky objects easy — even for beginners who might otherwise struggle with star charts or manual navigation — but still keeps the hands-on experience of moving the telescope manually. Observers tend to find it fun and engaging to follow the app’s guidance while learning the sky.
There are a few practical trade-offs to note. Because this is a manual Dobsonian, there’s no tracking — you’ll need to gently nudge the telescope to keep objects centered as the Earth rotates.
Some users also point out that the included accessories (like the basic focuser and eyepiece) are functional but might be upgraded later for more refined views, and that the large tube still requires some effort to set up and handle due to its size.
Despite this, the combination of large aperture optics and the StarSense app’s guided aiming makes the 10″ Explorer a highly capable and enjoyable telescope under $2,000 — especially for budding observers who want rich views without a steep learning curve.
7. Celestron Advanced VX 8″ Schmidt-Cassegrain Telescope
- 6" (150mm) aperture
- 1500 mm focal length

- 6x30 Finderscope
- StarBright XLT optical coatings
The Celestron Advanced VX 8″ Schmidt-Cassegrain Telescope brings together a classic 8-inch Schmidt-Cassegrain optical tube with a fully motorized Advanced VX equatorial GoTo mount, making it a compelling choice for observers who want both serious visual capabilities and entry-level astrophotography potential.
The SCT optical design provides a long focal length (~2032 mm) and large light-gathering area, delivering detailed views of the Moon, planets, star clusters, and brighter deep-sky objects with good contrast and resolution. The StarBright XLT multi-coated optics help maximize light transmission, enhancing overall image quality for visual observing.
What sets this package apart at its price point is the Advanced VX computerized equatorial mount with GoTo control, which includes a database of thousands of celestial objects and automatic tracking as Earth rotates.
This enables easier locating and following of targets compared with purely manual setups — a real plus for beginners who want less frustration learning star-hopping and for enthusiasts who want to start dabbling in astrophotography.
The mount also includes features like All-Star Polar Alignment and Periodic Error Correction, which improve tracking accuracy over time when you decide to image deep sky subjects.
However, there are some trade-offs to consider before choosing this telescope.
The long focal length typical of SCT designs means a narrower field of view, which can make wide-field deep-sky observing less optimal than with shorter focal length instruments — and setup plus polar alignment on an equatorial mount has a steeper learning curve than simple alt-azimuth GoTo or Dobsonian mounts.
Additionally, while the mount supports modest astrophotography, its payload limits and tracking precision aren’t as robust as higher-end imaging rigs, so long-exposure deep-sky photography might require future upgrades. Still, for backyard observing and basic astrophotography, this Advanced VX 8″ SCT bundle is a versatile performer that balances power, automation, and optics in one package.
Best Telescope Under $2000 - Buying Guide
Astronomy is one of the most enthralling activities in the world. Just ask an astronomer and watch as he attempts to explain the beauty of stargazing, albeit futilely because the experience of astronomy is just indescribable unless you personally experience it.
Whether you want to observe the planets and the stars, or delve deeper and explore deep space objects like nebulae, galaxies, comets and asteroids, then you are going to want to get the best scope that you can for your budget.
There are a lot of things to look out for, particularly telescope specs, functionality and features.
Features To Consider When Choosing A Good Telescope
Aperture
Aperture is the diameter, usually measured in millimeters, of the objective (primary) lens or mirror of the telescope. Essentially, the larger the aperture, the brighter images will appear, and the deeper into space you will be able to see.
Focal Ratio
Focal Ratio is a term that will be familiar to photographers, but it is important to certain astronomers, as well. This term is defined as the ratio between the focal length of the scope and the aperture.
A 100mm aperture 1500mm focal length telescope will have a focal ratio of f/15.
Focal Length
Focal length is the measurement, again in millimeters, from the objective to the eyepiece. This length directly affects the magnification potential of the telescope when paired with an eyepiece. The distance can be a literal linear measurement from the primary lens to the eyepiece, as with a refractor; or a theoretical distance based on how the light is bounced from primary to secondary mirrors and then into the eyepieces.
Magnification
Magnification is the number of times in size an object appears, compared to viewing it with the naked eye. A magnification of 32x means what you are looking at will look thirty-two times larger than when viewed unmagnified.
The magnification is calculated by dividing the eyepiece focal length into the telescope focal length. So, a telescope that has a 1500mm focal length, using a 25mm eyepiece will produce a magnification of 60x, and a 10mm eyepiece produces 150x.
As you can see, the longer the telescope focal length and the shorter the eyepiece focal length, the higher the magnification achieved.
Types Of Mounts
The mount is a very important part of the telescope. Some types of telescopes are better suited for a particular type of mount. There are 4 main types.
Alt-Azimuth Mounts:
Alt-azimuth mounts are the simplest type of mount, and they are similar to a camera tripod. They allow you to move the telescope up and down and side to side. But it can be difficult to track the stars and make precise adjustments. For this reason they are mainly suited for smaller, low-power telescopes.
Equatorial Mounts:
Equatorial mounts allow a telescope to track the sky as Earth rotates. They do this with motor drives but do not necessarily require a computer system to track, although some equatorial mounts are computerized for finding objects.
Most equatorial mounts are German equatorial mounts, which use counterweights to balance the telescope. This type of mount is versatile and breaks down into smaller pieces, making even large telescopes portable.
Dobsonian Mounts:
The dobsonian is a variation of the alt-az mount, designed for reflectors. Instead of using tripod legs, it uses a heavy base that is often made of wood. This is a stable design that doesn’t cost a lot and allows for more precise movements.
Fork Mounts:
A fork mount is designed for shorter tube telescopes (usually the compound type). They are motorized and do not require a counterweight since the telescope is balanced at it’s center of mass. But they are often heavier than other types of mounts.
Types Of Telescopes
Refractor Telescope
The simplicity and reliability of the design makes it easy to use and requires little maintenance. These are excellent for observing objects within our solar system—planets and the Moon and, with the right accessories, they can be used for terrestrial viewing. Since the optical system is basically a straight line, there are no obstructions from secondary mirrors as there are in Newtonians or catadioptrics.
Reflector Telescope
Utilizing a large primary mirror, the Newtonian gives you greater value per inch of aperture, since making a mirror is less labor-intensive than making lenses. However, to get the light focused and into an eyepiece, it is bounced from the primary mirror to a secondary mirror, placed near the front of the OTA facing the primary mirror and set at a 45-degree angle to the primary mirror, which sends the image into the side-mounted eyepiece.
This secondary mirror causes a slight obstruction to the light entering the OTA, which results in light diffraction and loss. Additionally, in traditional reflectors, the OTA is open to the elements, so they tend to require a certain amount of maintenance to keep the mirror free from dust, dirt, and pollen.
A variation of a Newtonian is the Schmidt-Newtonian, which places a corrector plate at the front, thereby helping to reduce spherical aberration and sealing the system for easier maintenance.
Catadioptrics
These are defined by their long focal lengths with short optical tubes. Utilizing a folded optical path, light enters through a thin, aspheric correcting plate, reflects off a spherical primary mirror at the back of the tube, where it is again reflected from a smaller secondary mirror located directly behind the front corrector plate and to the back to the optical tube and through an opening in the rear of the instrument to form an image at the eyepiece.
Conclusion
Our first pick for the best computerized GoTo telescope under $2000 is the Celestron – NexStar 8SE Telescope. Celestron’s NexStar 8SE 203mm f/10 Schmidt-Cassegrain GoTo Telescope is a powerful yet portable scope that can be used for observing everything from the Moon and planets to deep-sky objects like stars, galaxies, and nebulae, while maintaining the user-friendly interface of the telescope.
