Celestron StarSense Explorer: 8 Models Compared (2023)

The new Celestron StarSense Explorer telescopes use your smartphone to make it much easier to find planets, galaxies, and other objects to look at.

This helps remove much of the frustration that can occur when starting with astronomy – that it is too hard and takes too long to find things to look at.

But with eight different models, which is right for you?

In this article, we provide an overview of the differences between these telescopes so that you can understand the pros and cons of each. You can see a quick summary below, or read on for further detail:

Celestron StarSense Explorer Review & Comparison

There are eight different Celestron StarSense Explorer telescopes which we cover in more detail below.

Each is different but they all feature the StarSense Explorer technology that provides a great halfway point between computerized (GOTO) telescopes and manual ones (see FAQs below if you want more information on GOTO telescopes).

What these StarSense Explorer telescopes do is attach your smartphone then, using the app, scan the night sky above you, tell you what you can see on that particular night, and then guide you to it.

For example, if Saturn or the Andromeda galaxy are above you that night, you can select them on the app and then follow the arrows on the app to point the telescope at them.

Here is a quick video that shows how this works:

This is a great, innovative feature that takes advantage of the smartphone that you probably already own, and gives you something simpler and cheaper than a fully computerized telescope.

There are a few differences between each of the models, so let’s look at each of them in turn to help decide what’s right for you.

Celestron StarSense Explorer LT 80AZ

Starting with the Celestron StarSense Explorer LT 80AZ. You can take a number of its key characteristics from its name:

• Celestron = Manufacturer
• StarSense Explorer = the telescope range, as specified above
• LT = refers to how the smartphone is attached. The LT models like this simply have the phone sit on top of the telescope tube. The DX models have the phone sit off the side of the mount. This makes very little difference.
• 80 = the 80mm aperture of the telescope. This is the key measurement of its power and the views it can deliver. The higher this is, the better.
• AZ = refers to the alt-azimuth mount that comes with it. This is the component on top of the tripod with which you control where the telescope points and looks. Alt-Az mounts are best for astronomy and the simplest to use.

Not in the name, but worthy of note, is that it is a refractor telescope (as opposed to a reflector). This refers to the telescope’s build and shape.

Generally, refractors are less bulky and easier to operate. However, reflectors tend to give you more aperture (power) for the same price, with the downside being the bigger size and more cumbersome operation.

This model and the 102 AZ are refractors. The 114AZ and 130AZ are reflectors (as well as the two dobsonians).

Pros

• The lightest, most portable, and easiest to operate in the range
• Generally the cheapest (although check prices)

Cons

• The 80mm/3-inch aperture is the smallest of the range and will limit the brightness and clarity with which you can view night sky objects.

Overall, this is the most entry-level of the four telescopes in this range. It is the most portable (being the lightest) and is generally the cheapest. These reasons may make it the best option for kids. However, it has the lowest aperture, which will limit your viewing capacity.

It’s a great budget option, but if you have the space and intend to use it mostly at home then the 114AZ will give you more power for a similar price. If you prefer a smaller refractor, then the 102AZ below could work but will almost certainly cost more.

Key specifications

• Type: Refractor
• Aperture: 80 mm (3.25-inch)
• Focal Length: 900 mm (35-inch)
• Focal Ratio: F/11.3
• Weight: 9.2 lb (4.2 kg)
• Accessories: Two eyepieces (10 mm and 25 mm), 2x Barlow lens, smartphone dock, erect image diagonal, red dot finderscope, tripod.

Celestron StarSense Explorer DX 102AZ

In order of aperture, the Celestron Starsense Explorer DX 102AZ is the second most powerful in the range.

As noted above, the 102 in the name refers to the telescope’s aperture of 102mm (4-inch). This is the best measurement of a telescope’s capacity to provide good views.

It shares many of the characteristics of the other refractor in the range above in that it is smaller, lighter, and less cumbersome to operate, but it is more powerful with the larger aperture and you will be able to see more through it.

In addition, the faster focal ratio of F/6.5 will also make it better at taking astrophotography images.

Pros

• Most powerful refractor in the range
• Improved focal ratio for better photography
• Smallest telescope tube
• Less cumbersome than the larger models below

Cons

• Less power (aperture) than the two reflector options below
• Generally the most expensive

Overall, this is a great option if you prefer a smaller and less cumbersome refractor telescope, but want something more powerful than the 80mm option above. The downside is that it is generally more expensive.

Key specifications

• Type: Refractor
• Aperture: 102 mm (4-inch)
• Focal Length: 660 mm (26-inch)
• Focal Ratio: F/6.5
• Weight: 14.2 lb (6.4 kg)
• Included accessories: Two eyepieces (10 mm and 25 mm), smartphone dock, erect image diagonal, red dot finderscope, tripod.

Celestron StarSense Explorer LT 114AZ

The Celestron StarSense Explorer LT 114AZ is different from the models above in that it is a reflector telescope.

This means that it is larger and heavier. Also, you look into an eyepiece on the side, rather than at the bottom. Often this makes for more comfortable viewing with less stooping.

It has an aperture of 114 mm (4.5 inches). This is more powerful than the models above and will provide better views.

Pros

• More aperture and better views with 4.5 inch aperture
• One of the cheaper options alongside the 80AZ model

Cons

• Larger, heavier, more cumbersome, and less portable than the refractors above

Overall, this is a good option if you only have the budget for one of the cheaper telescopes and want more power.

The downside is that it is heavier and bulkier, so you should think about where you will use it and whether you value power over portability.

Key specifications

• Type: Reflector
• Aperture: 114 mm (4.5-inch)
• Focal Length: 1000 mm (39-inch)
• Focal Ratio: F/8.8
• Weight: 10.4 lb (4.7 kg)
• Included accessories: Two eyepieces (10 mm and 25 mm), smartphone dock, erect image diagonal, red dot finderscope, tripod.

Celestron StarSense Explorer DX 130AZ

Finally, the Celestron Starsense Explorer DX 130AZ model is bigger in terms of both physical bulk and aperture.

The 130 mm (5-inch) aperture is fairly large and will enable great views of planets and deep-sky objects when the night sky conditions are right.

Pros

• Large aperture for the best views of objects in the night sky

Cons

• Larger, heavier, more cumbersome, and less portable than the other models
• The most expensive (alongside the 102AZ)

Overall, this is the best option if you value a higher aperture for better views.

The downside is that it is generally in the higher budget range and that it is less portable, heavier, and bulkier.

Key specifications

• Type: Reflector
• Aperture: 130 mm (5-inch)
• Focal Length: 650 mm (25-inch)
• Focal Ratio: F/5
• Weight: 18 lb (8.2 kg)
• Included accessories: Two eyepieces (10 mm and 25 mm), smartphone dock, red dot finderscope, tripod.

Celestron Starsense Explorer 8″ Dobsonian

Brand new in 2022 are the two new Dobsonians in the range – this Starsense Explorer 8-inch Dobsonian, and the 10-inch version covered below.

In short, this is a brilliant telescope for viewing the night sky. The 8-inch aperture is huge and will provide few limitations to what you can see.

The downside to large dobsonians like this is the size – they are heavy and large. In fact, they are as big as a fairly small person, so this isn’t an option if you have limited space or want something portable.

Watch this video from Celestron for a quick overview of these two models and also to give you a good perspective of the size of them standing next to a grown man:

Pros

• Large aperture for great viewing

Cons

• Heavy and large. You need to consider where you will use it and store it.
• Not portable. You won’t be taking this on trips.

Overall, this is a brilliant option if you have the space to use it.

8-inch dobsonians are often highly recommended as the best telescopes and have been hard to get hold of in recent years due to shortages and supply chain disruptions around the world. Therefore this makes for a real (relative) bargain and a great option.

Key specifications

• Type: Dobsonian Reflector
• Aperture: 203 mm (8-inch)
• Focal Length: 1200 mm (47-inch)
• Focal Ratio: F/5.9
• Weight: 43.4 lbs (19.7 kg)
• Included accessories: 25 mm eyepiece, smartphone dock, red dot finderscope, base.

Celestron Starsense Explorer 10″ Dobsonian

Boasting a whopping 10-inch aperture, the Celestron Starsense Explorer 10″ Dobsonian is a beast of a telescope.

It has all the same pros and cons as the 8-inch model above, except that they are even more extreme – even higher power and viewing capacity, but also even heavier and bigger.

Pros

• Very large aperture for great viewing.

Cons

• Even heavier and larger. You need to consider where you will use and store it.
• Not portable. You won’t be taking this on trips.

Overall, this is a brilliant option if you want near-perfect viewing of planets and galaxies and have the space to use it.

Key specifications

• Type: Dobsonian Reflector
• Aperture: 254 mm (10-inch)
• Focal Length: 1200 mm (47-inch)
• Focal Ratio: F/4.7
• Weight: 54.8 lb (24.9 kg) (fully assembled)
• Included accessories: 25 mm eyepiece, smartphone dock, red dot finderscope, base.

Celestron Starsense Explorer DX 5

Newly added to the range in 2022 are this two Schmidt-Cassegrain (SCT) models – the DX5 and the DX6 (below).

This DX5 is Celestron’s classic 5-inch SCT telescope tube with a hand-operable mount and the Starsense Explorer functionality that allows you to connect your smartphone and allow it to guide you, like the models above.

The advantage with these models is that the Schmidt-Cassegrain design allows high aperture in a much more compact body.

Therefore these models will suit those where space is at a premium at home and would prefer something smaller, easier to store, and more portable.

Pros

• Good 5-inch aperture
• Trusted Celestron Schmidt-Cassegrain design
• Small and compact for the power it provides

Cons

• More expensive than other models like the Dobsonians that provide a better price-to-aperture ratio, but are also significantly larger

Overall, this is a great option if you want high power in a compact package and have the budget to pay a little more for this.

Also note, that the same telescope is also being sold as the Popular Science StarSense Explorer DX 5. This is exactly the same model from Celestron just being sold with different marketing and so is worth comparing the prices to find the best deal.

Key specifications

• Type: Schmidt-Cassegrain
• Aperture: 125 mm (5-inch)
• Focal Length: 1250 mm (49-inch)
• Focal Ratio: F/10
• Weight: 14.2 lb (6.4 kg) (fully assembled)
• Included accessories: 3 eyepieces, red dot finder, tripod

Celestron Starsense DX 6

The Celestron Starsense DX 6 is exactly the same as the DX5 above but has a larger 6-inch aperture instead.

You therefore get all the same advantages of a great compact Schmidt-Cassegrain telescope tube but with even higher power.

Pros

• High 6-inch aperture
• Trusted Celestron Schmidt-Cassegrain design
• Small and compact

Cons

• More expensive

Overall, if you have the budget then it makes sense to get the higher aperture DX6 over the DX5 as it will provide better views.

Again, just think about where you will use and store your telescope, as these DX models make great sense if you are short on space, whereas the other models are more inexpensive but bulkier.

Key specifications

• Type: Schmidt-Cassegrain
• Aperture: 152 mm (6-inch)
• Focal Length: 1500 mm (59-inch)
• Focal Ratio: F/10
• Weight: 27.9 lb (12.6 kg) (fully assembled)
• Included accessories: 3 eyepieces, red dot finder, tripod

Celestron StarSense Explorer FAQs

Are the Celestron StarSense Explorer good telescopes?

Yes, the Celestron StarSense Explorer telescopes are good. There are six different models to suit different budgets and priorities.

Celestron is one of the most reliable telescope manufacturers in the world.

What can you see with Celestron StarSense Explorer?

What you can see will improve according to the size of the aperture. The 80 mm model is the smallest with the weakest viewing capacity, and the 254 mm model is the largest with the best.

With all models, if the conditions are right you should be able to view the planets of the solar system and deep-sky objects like other galaxies. These views will be much brighter and clearer with the larger aperture models.

Which Celestron StarSense telescope is best?

If you disregard factors like size and portability, then the Celestron Starsense Explorer 10″ Dobsonian is the best as it has the highest aperture and will provide the best views.

Can you take pictures with the Celestron StarSense?

Yes, you can take astrophotography pictures with the Celestron StarSense Explorer telescopes using a smartphone adapter like this basic one or this premium one.

There is an issue though in that if you are using your smartphone attached to the telescope to use the StarSense technology then you won’t be able to attach it to the eyepiece to take a photo at the same time.

You’d have to either detach the phone and try not to move the telescope or use two separate phones.

Celestron StarSense Explorer vs Celestron AstroMaster Telescopes: How do they compare?

Some of the Celestron Astromaster telescopes use similar OTAs (telescope tubes) and similar AZ mounts.

They are completely manual though and do not have the StarSense technology and smartphone interactivity (although you may be able to replicate this with other adapters and apps.

Celestron StarSense Explorer vs Celestron NexStar Telescopes: How do they compare?

The Celestron NexStar telescope range are all full computerized compound / catadioptric telescopes.

This means they have the advantages of GOTO technology and are smaller telescopes in terms of physical size. They are generally more expensive though.

See our overview of all the different Celestron NexStar models.

Are Celestron StarSense Explorer telescopes computerized / GOTO?

Celestron StarSense Explorer telescopes are manual, not computerized, but their design gives you many of the advantages of this technology. For information:

• Computerized/GOTO telescopes feature a mount that operates where the telescope points and can find astronomical objects for you to look at automatically (usually operated by a hand controller). These are really good, but can be expensive and require a power source.
• Manual telescopes have a mount that you operate by hand and you usually have to locate things in the sky by looking for them with your eyes. These are cheaper, but make it much harder to find things, especially if you not an experienced astronomer.

The StarSense technology on these telescopes enables you to use your smartphone to give you much of what you’d get from a GOTO telescope. They won’t find things automatically for you, but they will search for what you can see and guide you to look at whatever planet or object you want to look at.

The other advantage is that no power source is needed.

Conclusion: Which Celestron StarSense Explorer is best for you?

In terms of which one is right for you, there are two key things to look at it – price and size:

• The 80AZ and 114AZ are the cheaper models. The 114AZ is heavier and more cumbersome but has higher aperture and you will see more through it
• The 102AZ and 130AZ are the mid-range models. The 130AZ is heavier and more cumbersome but has higher aperture and you will see more through it
• The 8-inch and 10-inch dobsonians are the top end of the range in terms of price and power, but they are also significantly less portable.

The fact that the price difference is fairly large actually helps narrow it down as, if you know your budget, you just need to pick what matters to you most:

• Smaller size and greater portability for the 80AZ or 102AZ refractors, or
• More power but larger and bulkier 114AZ and 130AZ reflectors, or
• Very high power but very large and bulky 8-inch and 10-inch dobsonians.

In summary:

1. If you have the space and plan to mostly use at home then the 130AZ is the best and will provide great views.
2. If you have the budget but value something lighter and more portable, then the 102AZ might be right for you.
3. If you want the cheaper option and have the space then the 114AZ might be for you
4. If you want the cheaper option but prefer something lighter and more portable, then the 80AZ might be best.
5. If you have the budget and space (and don’t care about portability) then the 8-inch and 10-inch dobsonians might be right for you.
