We’re staying focussed on good telescopes for viewing planets on this page. If you need a general purpose telescope, then head to our ‘Best Telescope of the Year‘ reviews instead.

You see, when deciding what telescope to buy to see the planets, you need a model particularly dedicated to the task. A telescope which has the special features making it ideally suited to observing the planets.

Do you know what those qualities are?


Well, keep reading and all will quickly become clear and you’ll be choosing the best planet watching telescope for your circumstances in no time!

What Makes a Great Telescope for Seeing Planets?

We can see at least five of the planets in our solar system with our naked eyes, and so it follows that every telescope can see them too, but…

There are qualities that make a perfect telescope for viewing planets, and we’ve listed them out for you here.

A ‘Slow’ Telescope is Best for Observing Planets

The planets (and moon) are the brightest objects in the night sky, which means light-gathering power is not always the most important thing for a good telescope to see planets.

All the light from a planet is coming from just a small patch of the sky (even the full moon is only half a degree across). If you only need to fill your eyepiece with the planet you’re looking at (and not lots of surrounding black sky) you only need a very small field of view.

Where is planet Jupiter tonight?

To get a smaller field of view, you need a longer focal length, which is the distance the light travels from mirror/lens to the eyepiece.  

Telescopes with a longer focal length generally have a higher focal ratio (the focal length divided by the aperture in mm).

So, when shopping for a good telescope to see planets, you need to be looking for a higher focal ratio, also known as a ‘slow’ telescope.

Anything with a focal length around 8 and above is known as ‘slow’ and is much more suited to planet observation than a wide-field, high low-ratio, ‘fast’ telescope.

Magnification thoughts for Viewing Planets

We can use a telescope’s highest magnification for viewing planets because of their brightness.

A telescope’s magnification is calculated by dividing its focal length by that of the eyepiece you’re using.

For example, take telescope with a focal length of 600mm. Insert a 25mm eyepiece and you’ll have a magnification of 24x (i.e. 600 / 25).

If you now but a 6mm eyepiece in the same telescope, you’ll have a magnification of 100x (i.e. 600/6).

However, although in theory this could go on for ever (e.g. 600x magnification if we use a 1mm eyepiece) there is an upper limit to a telescope’s magnification and it’s determined by how much light it collects. We are also limited, sadly, by the amount of magnification we can usefully use due to out swirling atmosphere.

When looking at a manufacturer’s claims on magnification, keep the following points in mind:

  1. The air quality (seeing) has a bigger impact as magnification gets higher. Jupiter can look almost like its underwater if viewed at very high magnification because of air turbulance. You should assume that only rarely will you be able to make use of more than 200x magnification
  2. Aperture size has an impact on how much magnification is theoretically possible with your telescope. A rule of thumb is your maximum magnification is 2x the diameter of your aperture in mm.A 100mm refractor, for example, is going to have a theoretical maximum magnification of 200x.
  3. The last thing to take into account is quality of optics. If you purchase a cheap telescope to see planets, assume a usable maximum magnification of around 70% the theoretical maximum.Using the example from point 2 above, 70% of our 200x magnification is actually 140x usable magnification.

Best Optics for a Planet Viewing Telescope

In common with all scopes, better optics make for a better experience.

Saturn will be more stunning with better optics (credit below)

Generally speaking, the best refractors for seeing planets will give a better view per mm of aperture than a reflector. This is because there’s no secondary mirror to obstruct the light, and the light focussing power of top-end lenses (those known as apochromatic, or APO) is more effective than from a reflector’s mirror.

APO refractors are shorter in length than lower quality achromatic refractors and so are more expensive.


They are so much better for viewing planets as the detail they bring out at higher magnification is not subject to chromatic aberrations.

Indeed, the difference is so marked that one site says an 80mm refractor of high quality optics will show you more than a 150mm reflector of low quality.

Good Mounts are Essential for Planetary Detail

You’ve already seen that we can look at planets with a small field of view.

The downside to that is a scene moving very quickly through your eyepiece. Trying to keep up with that movement without an equatorial mount will prove very frustrating!

The Orion StarBlast is the only telescope in our list with an alt-azimuth mount which keeps the price low for a wide-aperture refractor scope. However, it’s included in the list because it does have fine controls which make it easier to keep the planet you’re looking at centred in your eyepiece.

Ideally though, if your budget can stretch to it and you want to see those finer planetary details, make sure to get an equatorial or computer-controlled go-to mount.

Maksutov-Cassegrain: the Ultimate Telescope for Observing Planets?

Maksutov-Cassegrain (MKC) telescopes are perhaps ‘the daddy’ of telescopes for viewing the planets.

They are a variation on the Schmidt-Cassegrain design (which combines both a mirror and lens in a sealed unit) with a very long focal length – but in a much shorter tube.

This makes them very ‘slow’ and perhaps the best kind of telescope for studying the planets.

Now you know the features which make a telescope an ideal planet-watcher, it’s time to share with you our review of five great models which range from a cheap telescope to see the planets at one end, all the way to a high quality MKC that will cost over $1000!

Five of the Best Telescopes to See Planets

We’ve reviewed five telescopes for seeing planets to match every budget from below $200 to around $1000.

They are:

  1. Celestron StarSense Explorer LT 80AZ Refractor 
  2. Sky-Watcher Classic 6-inch Dobsonian
  3. Celestron StarSense Explorer DX 130AZ Newtonian Reflector
  4. Celestron Omni XLT 102mm Refractor

Approx Price: $190 (click here for today’s price in a new tab)

Focal Length: 900mm

Aperture: 80mm (3″)

Focal Ratio: f/11

Maximum Theoretical Magnification: 180x (5mm eyepiece)

Likely Useful Maximum Magnification: 128x (7mm eyepiece)

Celestron StarSense Explorer LT 80AZ telescope

The StarSense Explorer LT 80AZ uses Celestron’s unique StarSense technology to help you navigate your local night sky using nothing more than the power of your smartphone and its camera.

Download the StarSense app, enter your unique code and then attach your cell to the telescope in the special holder and you’re ready to go.

After a simple setup process (see the guide video, here) just enter any planet you’d like to see into the app and it’ll use your smartphone’s screen to guide you to the right place with pinpoint accuracy.

This is a small refractor, which is great for children to use and anyone who is content to enjoy the brightest objects in the night sky. Expect to see nice crater details on the Lunar surface, Jupiter’s moons and Saturn’s rings.

There’s no need for collimation or polar alignment and StarSense means you’ll be successful without any previous knowledge of the stars.

Pros (3)

  • StarSense technology makes seeing views easy
  • Easy to set up and go, even for total beginners
  • Child- and budget-friendly

Cons (2)

  • Small 3″ aperture only shows brightest objects
  • Mount prone to vibr

Our Rating:

Ideal For: Beginners with a small budget who just want to enjoy the views without learning to navigate the night sky.

• Sky-Watcher Classic 6″ Dobsonian

Telescope Type: Dobsonian Reflector

Mount: Dobsonian

Approx Price: $350 (click here for today’s price in a new tab)

Focal Length: 1200

Aperture: 152mm (6″)

Focal Ratio: f/7.8

Maximum Theoretical Magnification: 300x (4mm eyepiece)

Likely Useful Maximum Magnification: 300x (4mm eyepiece)

Sky-Watcher classic 6-inch Dob telescope

This 6-inch Dobsonian has focal length of 1200mm, giving it a focal ratio of f/7.9. This is a great telescope for viewing the planets that won’t break the bank.

It delivers high-quality viewing for the Moon and brighter planets in our solar system and, with its 6″ aperture, you’ll be able to see a decent amount of star clusters and brighter deep sky objects like Andromeda Galaxy.

Sky-Watcher’s large aperture for a relatively low price means you should expect to see Martian surface features like the polar ice caps and possibly even Jupiter’s Great Red Spot under good conditions.

Dobsonian telescopes are really simple to setup and use, and this is no exception. You will need to collimate the mirror from time to time to keep your focus sharp, but that’s easy to do with our guide.

You won’t find such a large, decent telescope for less money, which is why Dob’s are often the go-to model for backyard astronomers.

Pros (3)

  • Large aperture for a low price
  • Easy to set-up
  • Reveals lots of planetary details

Cons (2)

  • Bulky to move around
  • Cheap eyepieces and finderscope

Our Rating:

Ideal For: Maximising your budget! There is no better way to get more aperture for less money than with a Dob like this one.

• Celestron StarSense DX 130AZ Reflector

Telescope Type: Newtonian Reflector

Mount: Slow-motion AltAz with smartphone guidance

Approx Price: $400 (click here for today’s price in a new tab)

Focal Length: 650mm

Aperture: 130mm (5″)

Focal Ratio: f/5

Maximum Theoretical Magnification: 163x (4mm eyepiece)

Likely Useful Maximum Magnification: 163x (4mm eyepiece)

Celestron StarSense Explorer DX 130AZ

This model combines features from the first two on our planet-viewing telescopes list: a big aperture and StarSense technology.

There’s no hiding from the fact that this is a slightly smaller scope than the Sky-Watcher Dobsonian (above), nor that it costs about $50 more but – and this is significant – it comes with Celestron’s patented StarSense technology built in.

With this model, you have a decent 5″ aperture and the ability to attach your smartphone to it so that Celestron’s SmartSense app will guide you to find each planet with ease.

And we do mean each planet! With this telescope, you’ll be able to discover our most distant neighbors Neptune and Uranus for yourself.

Closer to home, you’ll be wowed with lovely views of Jupiter’s cloud bands and Galilean moons, as well as the crescent of Venus and Mercury (which is notoriously difficult to see), and the rings of Saturn.

The telescope is mounted on an altazimuth tripod with slow motion controls, which make it easy to track your chosen planet in the eyepiece as it moves across the sky.

If you choose to upgrade your eyepieces from the cheap 25mm and 10mm provided (which we recommend you do) it would be easy to see this as a telescope for life.

Pros (3)

  • StarSense technology to show you the planets
  • Large aperture for good levels of detail
  • Easy to use

Cons (2)

  • Low quality eyepieces
  • Mount prone to vibration

Our Rating:

Ideal For: Astronomers with a mid-range budget who want help to find the best views of planets available and to see more detail.

• Celestron Omni XLT 102mm Refractor

Telescope Type: Refractor

Mount: German Equatorial

Approx Price: $550 (Click here for today’s price in a new tab)

Focal Length: 1000mm

Aperture: 102mm (4″)

Focal Ratio: f/10

Maximum Theoretical Magnification: 250x (4mm eyepiece)

Likely Useful Maximum Magnification: 250x (4mm eyepiece)

Celestron Omni XLT 102mm refractor telescope

Refractors make for wonderful planet-watchers!

The downside of refractors is price. Making high quality lenses is more expensive than making the mirrors in a reflector so, inch for inch, refractors are more expensive.

However, unlike reflectors, they have no central obstruction coming from a secondary mirror, which means they deliver razor-sharp contrast, ideal for observing small planetary features.

In reality, this 4″ Celestron Omni XLT 102mm will deliver details that a 5″ reflector would struggle to match. Not only that but this model comes mounted on a German Equatorial mount so it can be upgraded for astrophotography in the future.

Expect this slow planet-watcher to show you details of craters and rilles on the Moon’s surface, clear splits between the bands on Jupiter’s disc, and even shadow transits of the Galilean moons.

Read our full-page review of the Omni XLT 102mm

Pros (3)

  • High contrast planet observation
  • Easy to setup and low maintenance
  • Good quality mount

Cons (2)

  • Only one eyepiece supplied (25mm)
  • Higher cost per inch of aperture

Our Rating:

Ideal For: Serious planet watchers and aspiring astrophotographers looking for the high contrast and details that come from a refractor’s lens.

• Celestron NexStar 6SE Compound Telescope

Telescope Type: Schmidt-Cassegrain

Mount: Motorized Alt-Az

Approx Price: $900 (click here for today’s price in a new tab)

Focal Length: 1500mm

Aperture: 6″ (150mm)

Focal Ratio: f/10

Maximum Theoretical Magnification: 375x (4mm eyepiece)

Likely Useful Maximum Magnification: 300x (5mm eyepiece)

Celestron NexStar 6SE compound telescope

Celestron’s NexStar range of catadioptric (compound) telescopes is perhaps the most popular on the planet, and the Celestron NexStar 6SE is the best selling of all the ‘SE’ computerized telescopes.

This might give you a clue that it is a fabulous all-rounder telescope – which is true (see our full review, here) – but that includes exceling with planetary viewing too.

The aperture is 6″, the same as the Dob featured above but this model is a compound telescope, a mix of lens and mirror which is specially configured to give a long focal length in a small tube.

All of which means it has a slow f/10 focal ratio, ideal for high magnification and tighter fields of view which are what you need to see intimate details on a planet’s surface.

The other huge benefit of the NexStar 6SE is that is has its own database and motorized tracking. Just tell the computer you ant to see Jupiter and it will slew the telescope to exactly the right spot.

If you have the budget and want a telescope that does all the work of finding the planet so you can spend your time enjoying its views, then this could be the perfect model. 

And, if you have a bit more cash available and want even more spectacular views of the planets, take a look instead at the NexStar 8SE. Click this link for today’s price (which opens a new tab) or click here for our full review

Pros (3)

  • Large aperture & huge focal length
  • High magnification for surface details
  • Easy to use goto and motorized tracking

Cons (2)

  • Compound telescopes like this are expensive
  • You’ll need a dedicated power supply for the tracking motor

Our Rating:

Ideal For: When money is not your primary consideration, but high quality and high magnification of the planets is!

The Best Telescopes for Seeing Planets?

It’s a really close call on which is best because it depends so much on our budget constraints. That’s why we’ve listed the models in budget order.

With the two StarSense models from Celestron, you’re tapping in to a new technology that makes backyard astronomy more accessible than it’s ever been. Your smartphone accurately guides the telescope.

There are two options for price. The LT 80AZ is smaller and cheaper and a great way to get into astronomy on a tight budget.

The DX 130AZ is larger and comes with better equipment and (of course) a larger price tag. It has the same simplicity of use but you’ll see more objects and smaller features with this model.

In between these two, we looked at the Classic 6″ Dobsonian from Sky-Watcher. The big selling points for the Dob are a huge focal length, lending itself to high magnification, and a decent aperture for very low cost. Oh, and they’re also about the simplest scope to use, just point and shoot!

The Celestron Omni XLT 102mm is a good quality refractor on a very good German equatorial mount. These are ideal for planet watching because they have really high contrast and clarity, unlike the reflectors on the list. However, they are more expensive.

Finally we looked at the Celestron NexStar 6SE and its big brother the 8SE. These very popular compound scopes produce high magnification and clear views, which is ideal for planetary observations. They also have a huge object database and motorized goto and tracking to make finding and following objects a breeze.

However, all of these features bump up the cost, so these are not low budget telescopes, but they are very good. 

We hope you’ve found a winner for your budget amongst these five planet-watching scopes!
