The bottom line

🔎 Celestron CPC Deluxe 1100 EdgeHD: if your budget can stretch to it, this telescope will give you an incredible view of the surface of any planet in our solar system, with magnification to spare. ★★★★½

Planetary imaging is a captivating hobby, and thankfully you can get started with any telescope that has a tracking mount. But if you're serious about capturing our neighboring worlds, a telescope with a large aperture is essential.

The CPC Deluxe 1100 EdgeHD's massive 11-inch main mirror resolves the surfaces of the most distant planets, revealing unprecedented detail. With greater resolution, it captures more data for imaging sensors. On more forgiving targets, such as Venus and Jupiter, it resolves remarkable detail, and even unskilled observers can spot landmarks such as deserts, polar ice caps, and even dust storms on Mars with relative ease.

The CPC mount is sturdy and reliable, providing excellent tracking for extended imaging sessions. It can also be converted into an equatorial platform with a wedge for deep-sky astrophotography. While it's a bit heavy, two people can quickly set up and dismantle this telescope in the field within minutes. 

Keep in mind that the package includes only one eyepiece, so you might want to budget for additional ones, especially if you're keen on planetary imaging. Fortunately, there's an upgrade option available if planetary imaging becomes a significant interest.

❌ You want a highly effective red dot finder: we thought that red dot finder on this telescope could definitely be improved, though it was fine for basic positioning.

The bottom line

🔎 Sky-Watcher Heritage-90P Virtuoso: as the most portable option on our list, this would be a great choice for those who like to take their telescope on stargazing trips out in the field. ★★★★½

The Heritage-90 Virtuoso may be compact, but its power is impressive. Utilizing two mirrors and a meniscus lens, it packs a substantial 1.25m focal length into a tube that's just 28cm long. With a comfortable 7mm eyepiece, it can achieve its maximum effective magnification. This portability sets it apart from some of the other models we've mentioned in this list.

The Maksutov-Cassegrain design is renowned for delivering sharp and high-contrast images, similar to a refractor telescope. This design is particularly well-suited for observing planetary surfaces and atmospheres, including the bands and moons of Jupiter. The Heritage-90 Maksutov-Cassegrain telescope exemplifies this design, offering excellent views of the planets at a relatively affordable price.

While the included red dot finder is not the best, the motorized Virtuoso mount makes it easy to point the telescope at objects in the sky. The smooth slewing controls allow you to track objects as they move across the sky, making it easier to keep them in view.

The mount can be upgraded at any time via Sky-Watcher's Synscan GoTo device, giving it the ability to find more than 40,000 objects in the night sky for you automatically. It can also track the sky to counteract the Earth's rotation, keeping your object of interest within the field of vision at all times. 

If you want to fast-track to the complete GoTo system and are interested in a more powerful telescope with a similarly compact design, you might want to check out the Heritage-90's big brother, the Skymax-127 Virtuoso GTI.

✅ You want a multifunctional telescope at an affordable price: the innovative smartphone mount will allow you to try your hand at some basic astrophotography along with your stargazing.

✅ You're mainly interested in viewing the planets and the moon: this telescope does a good job of bringing the planets and moon into sharp focus, but it doesn't let in enough light for deep-sky viewing.

Don't buy it if:

❌ You want to view deep-space objects: though this telescope can view some more distant objects, the aperture isn't up to true deep-space observation.

The bottom line

🔎 Celestron Inspire 100AZ refractor telescope: with some nice additional features like a smartphone mount and built-in red light, this telescope is a great way for beginners to start exploring the moon and planets. ★★★★

When we reviewed the Celestron Inspire 100AZ refractor telescope, we found it to be a great telescope for beginners looking to get a better view of the moon and the planets without breaking the bank. It sits at around $350, making it one of the most affordable options here, but that means you don't get a fancy motorized mount with this telescope. Instead, it comes mounted on a simple altazimuth mount that allows for manual movement via the panhandle, so you might want to pair it with a stargazing app if you've not yet got the confidence to navigate the night sky on your own.

If you're into astrophotography, this telescope has a pretty cool feature — the lens cap doubles as a smartphone mount, so you can use your phone to take breathtaking photos of the planets and the night sky.

The telescope is lightweight and we found it to be very easy to set up and take down. However, the optical tube is 26 inches/660mm long, so it does take up a bit of space.

While the 4-inch aperture doesn't capture enough light for distant space objects, this telescope provides a good view of planets, especially with the 20mm eyepiece. We observed detailed moon craters and even caught a glimpse of Andromeda (M31) and some bright star clusters. While it may not be the best telescope out there, we think it's a reliable choice for beginners and offers good value for its price, with some fun extra features.

✅ You want something sturdy: the mount on this telescope is well matched to its weight and feels solid and substantial.

✅ You're looking for an equatorial mount: this telescope package comes with an effective equatorial mount that can even be operated one-handed. 

Don't buy it if:

❌ You're particularly interested in deep-space objects: this telescope gives detailed views of the planets, but isn't quite up to viewing deep-space objects.

The bottom line

🔎 Celestron Omni XLT 102: this telescope offers a nice combination package that feels sturdy and robust. It includes an equatorial mount and can give you a detailed view of the planets. ★★★★

The Celestron Omni XLT 102 is a unique package featuring a high-quality telescope and mount combination. It's easy to set up, requiring no tools, making it an excellent choice for both beginners and experienced astronomers.

The 4-inch F/10 achromat gives fine views, and its focal length makes it a good match for some of the best planetary eyepieces. Unfortunately, only one is supplied in the box, but with the addition of a 10mm and Barlow lens (take a look at our best eyepieces guide), you can achieve a magnification of 36x, 72x, 100x and 200x. At this top end, the Omni XLT 102 will show you some lovely details on our neighboring planets.

Celestron also sells a 120mm model (read our Celestron Omni XLT 120 review) and a 150mm version of the same telescope. However, it's worth noting that all three models come with the same CG-4 equatorial mount, and the larger ones may approach the weight limit of the mount. Nevertheless, the mount feels stable during use and quickly dampens any vibrations.

Being an equatorial mount (where the polar axis is parallel to the Earth's rotation), it takes some getting used to, but once you do, you'll find that it makes planet tracking simple and easy to do one-handed. For those looking to go fully hands-free, Celestron offers a separate dual-axis auto-tracking upgrade kit that can be installed at any time.

✅ You're looking for excellent optics: the images produced by this telescope are sharp, vibrant and detailed.

✅ You want a larger aperture: the 7.1-inch primary mirror on this telescope performs incredibly well.

Don't buy it if:

❌ You want something that's very portable: although this telescope is relatively compact, it's still quite heavy to move around.

❌ You're on a tight budget: this is quite a pricey telescope and there are plenty of more affordable options out there.

The bottom line

🔎 Sky-Watcher Skymax-180 PRO: this telescope is a beast when it comes to optics and produces incredible views of the planets and moons, but it's quite an investment. ★★★★

The Sky-Watcher Skymax-180 PRO is designed specifically for exploring the solar system. Its high-resolution, long focal-length optical system delivers flawless views of planets, capturing vibrant details similar to a more expensive apochromatic refractor. With a 7.1-inch primary mirror, it also provides enough light grasp to reveal many of the moons in our solar system. 

While the included 2-inch/28mm eyepiece doesn't fully unlock the telescope's potential, we'd recommend investing in a more powerful 8mm or 10mm planetary eyepiece that will enhance its formidable optics.

For maximum accuracy and stability, the Skymax-180 PRO is mounted on a HEQ5 PRO equatorial mount — a heavy-duty mount that is designed to carry large payloads. This makes it ideal for a variety of photography uses, including high-resolution planetary and lunar imaging, as well as deep-sky imaging.

If you plan to purchase another telescope in the future, it is beneficial to 'over-mount' the scope. This means choosing a mount that is rated for a heavier payload than the telescope you currently have. This provides additional stability, which is especially important at higher magnifications.

The combination of the Skymax-180 PRO and the HEQ5 PRO mount is a popular choice among visual observers and astrophotographers alike. It is a versatile and powerful setup that can be used for a wide range of applications.

The bottom line

🔎 Celestron AstroFi 102: this telescope would suit beginners who want to use an app and plan on taking their telescope out and about. ★★★½

The Celestron Astro Fi 102 is perfect for beginners who enjoy technology and want a closer look at planets. Once you've completed the initial setup of the motorized mount (which may take a bit of time), it becomes user-friendly with the SkyPortal app, compatible with both iOS and Android.

The app, which we found to work seamlessly during our Celestron Astro Fi 102 review, features approximately 100k celestial objects, which you can 'instruct' the instrument to slew automatically. It slews quickly and quietly, and you can even use a USB video game controller to position the scope, which is a desirable feature for gamers.

While the telescope may not feel like the most expensive product on the market, the materials used in its construction make it lightweight and portable, making it ideal for transporting to stargazing locations. Nevertheless, it's still important to protect it effectively during transport to avoid inflicting any damage.

With the right eyepieces, this telescope offers clear, close-up views of the Moon, Saturn's rings, Mars, Jupiter, Uranus, and Neptune under the right conditions.

✅ You like using an app: the StarSense app makes it easy to operate this telescope and it even comes with a built-in smartphone holder.

Don't buy it if:

❌ You want precise optical clarity: this telescope does suffer from some chromatic aberration on bright objects

❌ You want to view deep-sky objects: while it's good for viewing the planets, this telescope can't offer a proper view of deep-sky objects.

The bottom line

🔎 Celestron StarSense Explorer LT 114AZ: this is a good entry-level telescope for seeing the planets, but the optics won't allow you to see further objects like galaxies. ★★★

From our Celestron StarSense Explorer LT 114AZ review, you'll see that this telescope is best used to view the moon and planets, as it's designed to give a high magnification of bright objects.

While this is an affordable telescope, some sacrifices have been made in terms of image quality. When viewing bright objects, you may notice some chromatic aberration (color fringing), and the colors may not be as accurate as those produced by some of the more expensive models.

The StarSense app streamlines the alignment process, making it quick and easy, which is a dream for beginners. The telescope operates as a 'push to' scope, meaning the mount doesn't automatically turn to locate your selected target. Instead, arrows on your phone screen guide you to the right position. Just follow the instructions on the screen, turn the telescope accordingly, and once a bullseye appears on your screen, your target will be centered in your field of view. Keep in mind that there are no slow-motion controls, so achieving precise adjustments may require some practice.

With the included Barlow lens, you will be treated to spectacular views of Saturn, Jupiter and the moon, but don't count on this scope to see objects in deep space because it doesn't allow enough light.

Best telescopes for seeing planets 2023: Frequently Asked Questions

Which telescope is best for viewing planets: Refractors or reflectors?

When shopping for a telescope on a budget, there's an argument to be made for choosing a smaller refractor over a similarly priced but larger reflector. This is because the secondary mirrors and struts in Newtonian reflectors can distort the incoming light, reducing image contrast.

For many dedicated planetary observers, a large refractor is the ideal telescope. However, refractors can be bulky, heavy, and expensive, so probably not a purchase to make if you aren't in it for the long run.

Compound telescopes, such as Maksutov-Cassegrains and Schmidt-Cassegrains, offer a good compromise, providing good image quality in a relatively compact and affordable package.

Ultimately, the best way to decide which type of telescope is right for you is to try both and see which one you prefer.

What telescope eyepiece do I need to view planets?

There are also other optical accessories to consider when shopping for a planet-hunting telescope. Eyepieces with greater magnifications can help get larger views of the tiny planets, you should opt for one with medium to high magnification.

Astronomers should also consider Barlow lenses to help attain high magnifications of between 120-250x (within the optical limit of the telescope). This will allow you to observe in the sweet spot on most nights when the seeing is average. Our list includes some of the best telescopes for seeing and capturing planets.

What telescope do I need to see Saturn's rings?

This all depends on the telescope and eyepiece combination. Telescopes have a focal length and so do telescope eyepieces. But telescope eyepieces also have an apparent field of view, which when calculated alongside the focal lengths, determines the true field of view when looking through the eyepiece and telescope.

A simple way to get started calculating which telescope or eyepiece you need to see Saturn's rings is to use the following basic formula:

Telescope focal length / eyepiece focal length = Magnification

Apparent field of view / Magnification = True field of view

You can then compare the true field of view of the combination against the size of any object you wish to observe to see how well you'll be able to view it, including Saturn's rings, Jupiter's red spot and more. But remember that surface brightness and atmospheric conditions as well as weather will ultimately decide how well you can view any night sky object, including a planet.

How we test the best telescopes for seeing planets

To guarantee you're getting honest, up-to-date recommendations on the best telescopes to buy here at Space.com we make sure to put every telescope through a rigorous review to fully test each instrument. Each telescope is reviewed based on many aspects, from its construction and design, to how well it functions as an optical instrument and its performance in the field.

Each telescope is carefully tested by either our expert staff or knowledgeable freelance contributors who know their subject areas in depth. This ensures fair reviewing is backed by personal, hands-on experience with each telescope and is judged based on its price point, class and destined use. For example, comparing a 10-inch Dobsonian to a 2.76-inch refractor wouldn’t be appropriate though each telescope might be the best pick in their own class.

We look at how easy it is to set up, whether computerized or motorized mounts are reliable and quiet, and if a telescope comes with appropriate eyepieces and tripods. We also suggest if a particular telescope would benefit from any additional kit to give you the best experience possible.

With complete editorial independence, Space.com are here to ensure you get the best buying advice on telescopes, whether you should purchase an instrument or not, making our buying guides and reviews reliable and transparent.

Telescope Glossary

Aperture: Diameter of the primary mirror or lens, which allows a telescope to collect light.
Field of view: Area of sky visible through the eyepiece.
Focal length: A telescope's tube length. Short focal lengths offer a wide field of view and a small image.
Focal ratio: Also known as the telescope's speed. Small focal ratios provide lower magnifications, wide field of view and a brighter image.
Magnification: Relationship between the telescope's optical system and the eyepiece. 

Unlike the deep sky, which remains almost unchanged throughout our lives, the planets constantly bring us new and sometimes surprising reasons to look again. They're easy to find and inspiring to take in — real worlds that our descendants or even we may visit one day. 

Any telescope can make them look impressive, but a well-tuned high-contrast instrument is what is needed to really do them justice, and you'll be thankful to have one to hand when something special occurs, like the arrival of an incredible gas giant storm, or a night of exceptionally steady seeing that invites you to max out the power. If you plan to take your own astrophotos, it's well worth considering a telescope mount with tracking capability, altazimuth or equatorial — both are suitable for short exposures. At such long focal lengths, the Earth's rotation quickly moves things out of the field of view, and dedicated planetary imaging cameras have small sensors. Regardless of which telescope you choose, you're in for an exciting new hobby as a Solar System explorer. Enjoy the magnificent highlights of our celestial neighborhood.
