The 9 Best Celestron Telescopes

1. Celestron StarBright XLT Telescope – Best Overall

Celestron CPC 1100 StarBright XLT 2800mm Telescope

The Celestron CPC 1100 StarBright XLT 2800mm Telescope is the crown jewel of the Celestron telescope fleet. It has a massive, 11-inch aperture, which is more than enough to make even the dimmest celestial objects visible, even in areas full of serious light pollution. It also includes a 9×50 finderscope, which is as powerful on its own as some full telescopes. There’s a heavy-duty tripod, which greatly reduces vibrations and makes it easy to align this telescope with objects in the nighttime sky.

However, the best thing about this model may be its use of GPS to automatically find and track objects. You’ll be able to see distant objects even if you’re an amateur astronomer, and with its onboard library of more than 40,000 objects, you’ll never run of out new things to see. The one downside is that it’s heavy, weighing 92 pounds between the telescope and the mount. Because of this, it’s not the most portable telescope out there. Still, if you’re looking for a telescope that will allow you to see practically anything in the night sky, you’ll like this model.

All in all, we think that this is the best Celestron telescope on the market right now.

  • Very large aperture
  • Powerful finderscope
  • Heavy-duty tripod
  • GPS-connected
  • Weight

2. Celestron NexStar 4 Telescope – Best Value

Celestron NexStar 4 SE Telescope

If you’re looking for a telescope with good performance, but a price tag that won’t cause heart attacks, the Celestron NexStar 4 SE Telescope may be the right choice. There’s a large, four-inch aperture, which isn’t anywhere near as large as the top selection on our list, but that’s more of a testament to how large that one is. Like our top pick, this model comes with an automated mount, so once you have it aligned, you’ll be able to have this telescope find any of the 40,000+ objects in its library. It’s also easy to set up, so if you don’t want a complicated assembly process, you don’t have to worry with this model.

However, the best thing about this model may be its price. Despite coming with an automated mount, it costs about 16 percent of what our top option costs, making it a great investment overall. The one thing that keeps it out of first place is that it’s not GPS-enabled, so you do have to do some alignment yourself. Still, that’s not a big issue, given how much money you’ll save.

  • Large aperture
  • Automated mount
  • Easy setup
  • Great price
  • Alignment can be tricky

3. Celestron 21035 Travel Telescope – Budget Buy

Celestron 21035 70mm Travel Scope

The Celestron 21035 70mm Travel Scope is the first one on our list that qualifies as truly portable. It comes with a backpack that’s custom-designed for carrying this telescope and its tripod. Taking this telescope camping, or to a local park, is a quick and easy task. It has a 70-millimeter lens, which isn’t massive, but it’s still respectable. Also included are two eyepieces, with 20x and 40x magnification. This is a far cry from the theoretical maximum magnification of 600x found in our top model, but it’s still enough to make out most of the objects in our solar system.

This one can also be had for a low price. It’s less than a quarter of the price of the second-place one, so this is the telescope to get if you’re looking for the ultimate budget buy. You can’t always get great quality and a great price, but this scope provides both. The only thing we don’t like is that the tripod can be shaky. Still, if you’re looking to save money and get a telescope with great clarity, you’ll like what this model provides.

  • Travel-ready
  • Large lens
  • Two eyepieces
  • Fantastic price
  • Underwhelming tripod

4. Celestron NexStar 130SLT Telescope

Celestron NexStar 130SLT Computerized Telescope

The Celestron NexStar 130SLT Computerized Telescope is another great choice for Celestron fans. It has a computerized mount like the top two models on our list, enabling you to find objects in the night sky, even if you have little astronomy experience. There’s a very large 130-millimeter focal length, which is phenomenal for the price. That’s large enough to let you see just about anything in our solar system, and several deep-space objects as well. It also comes with two high-quality eyepieces. These let you see at 26x and 72x magnification, respectively, so you’ll be able to make the most of your telescope with the included eyepieces.

This scope is arguably the best on our list for photography. While you’ll need to purchase a camera adapter separately, this model has a great reputation in the astronomy community for allowing both experts and beginners to take incredible pictures. The one downside is that it’s a reflector telescope, which means you’ll need to run it through an alignment process called collimation. Other than that, there’s a lot to like about this one for both beginners and experts.

  • Computerized operation
  • Very large aperture
  • Good eyepieces
  • Great for photography
  • Requires collimation

5. Celestron 114LCM Computerized Telescope

Celestron 114LCM Computerized Telescope

The Celestron 114LCM Computerized Telescope is a good telescope but has some peripheral issues that cost it a few positions on our list. On the plus side, it’s computerized like a lot of the top-performing models. If you haven’t learned how to find stars, nebulas, and other planets in our solar system, this telescope can guide you to them once it’s been aligned. It has a very large 114-millimeter aperture, so you can get great detail that smaller telescopes just can’t match. Plus, it comes with two eyepieces, so you’ll be able to see celestial objects at 60x and 167x magnification right out of the box.

However, this model isn’t power-efficient. In practice, that means it burns through batteries at an alarming rate. If you’re planning to use it a lot, it makes sense to invest in an AC power adapter, though that drives up the price. It also suffers from a shaky mount, so you have to be very careful when making adjustments. This is a decent telescope, but most people will find that they can get better value for the money with a different telescope.

  • Computerized
  • Very large aperture
  • Two eyepieces
  • Burns through batteries easily
  • Shaky mount

6. Celestron AstroMaster 70AZ Refractor Telescope

Celestron 21061 AstroMaster 70AZ Refractor Telescope

The Celestron 21061 AstroMaster 70AZ Refractor Telescope is positioned as an entry-level telescope, but there are some reasons that beginners could be better served by a different scope. This one does come with an alt-azimuth mount, which is better than expected on a telescope at this price point. That makes it easy to align this telescope and keep it aligned with objects in the night sky. It also has a reputation for being very easy to assemble, and it’s not a reflector telescope, so you’ll never have to collimate it. Plus, it comes with 45x and 90x magnification due to its great included eyepieces.

Still, some problems make it less than what one would hope for from the Celestron brand. Like a lot of low-priced telescopes, the mount is shaky and becomes especially problematic when the wind is blowing. Something else to consider is that 70 millimeters is fairly small as far as telescopes go. It could compromise your ability to see objects outside our solar system, and you won’t get great detail looking at other planets. That means many people will be disappointed with their purchase, despite the low price.

  • Smooth positioning
  • Easy setup
  • Two eyepieces
  • Shaky tripod
  • On the small side

7. Celestron PowerSeeker 127EQ Telescope

Celestron PowerSeeker 127EQ Telescope

The Celestron PowerSeeker 127EQ Telescope has the potential to be one of the best that an amateur ever owns. With an incredibly large 127-millimeter aperture, it’s one of the largest telescopes on our list. If you want to view other planets in our solar system, this one can get the job done. Its design also lends it a phenomenal 1000-millimeter focus length, which is far longer than most consumer telescopes, and means you have a high theoretical maximum magnification. Also included is a Barlow lens, which triples the magnification provided by the telescope and the eyepiece you use. This allows between 150x and 450x magnification, which is very high for a consumer telescope.

However, it has some of the problems that tend to come with low-priced telescopes. It has a shaky tripod, which means you have to be gentle when focusing. Otherwise, the image will be blurry. This is a reflector telescope, so it requires collimation. Unfortunately, it’s not the easiest model to collimate. If you’re patient and willing to invest in a better tripod, you can get good use out of this scope. Otherwise, you’ll probably dislike it.

  • Very long focal length
  • Very large aperture
  • Includes Barlow lens
  • Poor-quality tripod
  • Difficult collimation

8. Celestron ExploraScope Reflector Telescope

Celestron ExploraScope 22103 114AZ Reflector Telescope

The Celestron ExploraScope 22103 114AZ Reflector Telescope is priced like a beginner’s telescope, but it has some shortcomings that make it a poor choice except for those who really want to learn. On the plus side, it has a stable mount and tripod, so you won’t have to worry as much about that part interfering with your operation. There’s a 114-millimeter aperture, which is fairly large for the price. The included 2x Barlow lens is a nice touch, increasing what you can do with this telescope and its eyepieces without driving the price up too much.

New users should hesitate before buying this telescope, since it requires frequent collimation. It doesn’t stay aligned as well as other models, and this level of maintenance may be more than most casual users want. It also lacks detailed documentation, so it’s not as easy to set up and use as other options on our list. The big problem is that it isn’t large enough for advanced users, but doesn’t have the ease of use of entry-level telescopes. Overall, it’s okay, but most experts and beginners will find that it doesn’t meet their needs.

  • Stable mount
  • Large aperture
  • Includes Barlow lens
  • Requires frequent collimation
  • Not enough documentation for beginners

9. Celestron Astro Fi 102 Telescopes

Celestron Astro Fi 102

The idea of a wi-fi-enabled telescope is good, but the Celestron Astro Fi 102 fails to live up to most users’ expectations. Its big selling feature is that it comes with a wi-fi card, so you can connect it to your home network or to a cellphone, and control it through your smartphone. There’s also a cellphone adapter, which allows you to take pictures and use your cellphone as a screen so multiple people can view the image at once.

However, that means you can’t use your smartphone as a screen and use the app that controls the telescope at the same time. That’s only the first of its major problems. The app Celestron provides is prone to freezing and crashing, which makes using this telescope a pain. It also doesn’t have an AC power supply, and given its wi-fi capabilities, it burns through batteries very quickly. It also has some cheap parts that don’t seem up to the standards found on other Celestron products. Overall, this model represents a cool concept, but it’s likely to leave people frustrated.

  • Wi-fi ready
  • Smartphone adapter
  • Some cheap parts
  • No AC power supply
  • Poor app performance
