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 in our full review) 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 tricky objects 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 vibrations

Our Rating:

Sky-Watcher Classic 6″ Dobsonian
– Best for Seeing Planetary Details

  • Telescope Type: Dobsonian Reflector
  • Mount: Dobsonian
  • Approx Price: $460 (click here for today’s price in a new tab)
  • Focal Length: 1,200mm
  • 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 1,200mm, 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
  • Supplied with cheap eyepieces and finderscope

Our Rating: 4/5

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
– Best Overall

  • Telescope Type: Newtonian Reflector
  • Mount: Slow-motion AltAz with smartphone guidance
  • Approx Price: $450 (click here for today’s price in a new tab)
  • Focal Length: 650mm
  • Aperture: 130mm (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), but it costs about the same, 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: 5/5

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
– Best for Optical Quality

  • Telescope Type: Refractor
  • Mount: German Equatorial
  • Approx Price: $660 (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: 4/5

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
– Best for Planet Tracking

  • Telescope Type: Schmidt-Cassegrain
  • Mount: Motorized Alt-Az
  • Approx Price: $1,100 (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: 4.5/5

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

Buying Guide for Planet-Viewing Telescopes

Frequently Asked Questions

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.

Is a Long or Short Focal Length Better for Observing Planets?

Generally, longer focal lengths are better in telescopes for viewing the planets.

The planets are amongst 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. I.e., we’re not as worried about the aperture of the telescope as we would be for hunting galaxies.

Instead, we’re more concerned with the planetary details we can see.

Since all of the light from a planet comes from a tiny patch of the sky, you only need a very small field of view to fill your eyepiece with the planet. Jupiter, the largest planet, is less than 1/60th of a degree wide at its largest.

If you’re field of view is a whole degree wide, then Jupiter will look a bit lost in the middle of it, whereas, if your field of view is 1/10th of a degree, then Jupiter will look much larger in your eyepiece. So, a smaller field of view is an advantage for exploring the planets.

Mighty Jupiter is just 50 arcseconds wide in our sky (source)

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 look 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.

What Magnification Will I Need to See the Planets?

Because the planets are so bright, we can normally use a telescope’s maximum theoretical magnification to view them. In reality, they are so big and bright that even modest magnification will show them off. You’ll be able to see the crescents of Mercury and mars, the bands of Jupiter, and the rings of Saturn with very little magnification.

To see more refined details, like the snow caps of Mars and Jupiter’s Great Red Spot, you’ll need high magnification, good seeing conditions, and decent optics.

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 put 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 forever (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 turbulence. 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 cheaper telescope to see the 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.

What Are the Best Optics for a Planet Viewing Telescope?

In common with all scopes, better optics make for a better experience. But we think – especially if you’re new to astronomy – it won’t matter what kind of optics you have, you’ll be blown away by your first views of Mars, Jupiter, and Saturn when you see them through your new telescope!

Saturn looks stunning through, even in a small scope (source)

However, if you’re not so new and you want to get more serious about your planet viewing, or even imaging, then optics are worth paying a little more attention to.

Generally speaking, refractors 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 more expensive than lower quality achromatic refractors, but…

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.

What’s The Best Mount for Seeing Planetary Detail?

You’ve already seen that we can look at planets with a small field of view but the downside to that is a scene that moves very quickly through your eyepiece. An ideal mount is one without too much vibration and that’s easy to guide gently, such as with control wheels.

The ideal choice, if your budget can stretch to it and you want to see those finer planetary details, is to invest in an equatorial or computer-controlled mount because these will track a planet’s movement across the sky much more smoothly.

Why Do People Say That a Compound Telescope is Best for Planet Watching?

Compound telescopes, such as the Schmidt-Cassegrain design (which combines both a mirror and lens in a sealed unit) of the NexStar 6SE, above, pull off the trick of having a very long focal length in a much shorter tube.

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

The downside of this physics parlour trick?

Cost!

A decent compound telescope will cost more than $1000, as you can see in our list above.

Summary, and Our Number One Choice

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. That’s why we think this is the very best telescope for looking at planets.

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!
