With the StarSense Explorer, Celestron has reinvented the manual telescope, as it is the first telescope that uses your smartphone to analyze the night sky and calculate its position in real time.
With the StarSense Explorer - the first telescope that uses your smartphone to analyze the sky and calculate its orientation in real time - Celestron is redefining the manual telescope. The StarSense Explorer is ideal for beginner amateur astronomers, as the application is user-friendly and includes detailed educational material (tutorial). You will feel like you have your own personal guide to the night sky.
Forget complicated star maps, inaccurate planetarium apps, and expensive automated mounts. With Celestron StarSense Explorer telescopes, finding celestial objects is easier, faster, and more accurate than ever. Within minutes of setting up your telescope, you'll confidently navigate the sky.
Place your smartphone on the special base located on the optical tube and launch the StarSense Explorer app. Once the smartphone is aligned with the telescope, a process that takes only two minutes, the StarSense Explorer creates a list of visible celestial objects (above the horizon) at that moment. Once you select the object you want, arrows appear on the screen, indicating where to point the telescope. When the object is ready for observation, the reticle turns green.
The StarSense Explorer works with most modern smartphones, including the iPhone 6 and most models made from 2016 onwards running Android 7.1.2. For a complete list of compatibility, click here.
The StarSense Explorer uses patented technology and your smartphone to accurately determine where your telescope is pointed in the night sky. An algorithm called LISA, similar to those used by orbiting satellites to correct their orientation, helps the app match the star patterns it detects in the sky with the stored data in its database.
There are other astronomy apps that claim to help you find objects in the sky, but they rely solely on the phone's gyroscopes and accelerometers, which are not as precise as LISA technology. No other app can accurately tell you when your target is centered in your eyepiece's field of view.
It is an extremely stable altazimuth mount, which provides a solid base of support for the optical tube of the Explorer DX. By releasing the axis brakes, you can roughly point the tube towards the target, while the micromotion controls on both axes help you bring it to the center of the field of view. As celestial objects shift in the sky (actually, it is the Earth that is rotating), you can track them by turning these controls. The mount rests on an adjustable-height tripod.
With a primary mirror of 130 mm, this telescope has a sufficiently large light-collecting capacity to reveal impressive details of celestial objects. You can expect clear and bright views of the four Galilean moons, the cloud belts and the Great Red Spot of Jupiter, the moons of Saturn, the Orion Nebula's Trapezium Cluster, and the beautiful Pleiades star cluster. The high reflectivity coatings on the primary and secondary mirrors further enhance the image quality.
Even if you live in a city where the sky suffers from light pollution, the StarSense Explorer is advanced enough to distinguish Jupiter, Saturn, Venus, the Orion Nebula, double stars, and some other well-known celestial objects.
But if you can transport the telescope to a somewhat darker location, you will be able to see more objects. With this 5-inch telescope under a relatively dark sky, the Andromeda Galaxy, the open star cluster of Hercules, and many other attractions will be at your disposal.
The entire telescope system weighs about 8 kg, so it is highly portable and you can easily take it with you the next time you go camping or simply to a remote dark location.
Important: Check the compatibility of the application with your device HERE.

This telescope is not at all bad, and as a 12-year-old amateur astrophotographer, I would say it is a very good starting point for beginners. It is relatively easy to use and set up, as it uses an altazimuth mount, which I am familiar with. The only issue is that it takes a little effort to secure the front mirror so that you can see what the telescope is pointing at. Meanwhile, the starsense explorer app is very helpful in locating star clusters or nebulae. Planets are easy to locate with the naked eye and capture with this telescope. Moreover, with that app, you can even place your phone in the starsense holder and go through an alignment process to have it show you arrows pointing approximately where the telescope is pointing. Excellent!!
The hobby of astronomy observation is quite expensive, so this particular telescope is a relatively affordable way to get started with satisfactory results.
The Starsense Explorer app is quite helpful in the initial steps, but it requires patience for familiarization and the first alignment.
A basic requirement for good results is suitable weather conditions, as well as proper mirror alignment.
This specific telescope model is a Newtonian Bird-Jones, and one of its main drawbacks is the collimation process, which needs to be done frequently, especially if the telescope is moved often. There are manual collimation methods, but for beginners, purchasing a laser collimator is helpful.
Important note: In order for the laser collimation to work on Bird-Jones telescopes, the corrector lens inside the focusing tube must be removed first.
Good evening, the telescope does not live up to its promises. It requires many additional accessories in order to find and see the targets. I managed to see the Orion Nebula, but I am in an area with no light pollution, and even then, the situation is terrible. It is better to spend more money, around a thousand or more, in order to have a decent telescope
You need a telescope if you want to observe something beyond the moon. It takes a lot of patience to learn how to aim, the trick with the mobile app is good but in the end it requires searching, it roughly takes you to the place where you need to do research. Observing in the city is tragic (beyond the moon) due to light pollution and heat from the rooftops of apartment buildings.
In general, I am still searching but I have not been able to see a star or a nebula even in the countryside. Much more detail is needed for planets like Saturn's rings, for example.
For 300+€, I expected something better, especially for beginners.
Guys, the telescope is perfect, easy to set up, includes step-by-step instructions, and comes with accessories like lenses and targeting through the smartphone app. So, it's easier to locate the point you want to see, like Saturn for example. Check out the photo I captured with my phone's camera.
The construction of the base is quite good, but it's not as stable in certain areas. It needs a more sturdy construction here. Also, the app doesn't work properly on some smartphones, despite having the Android version. It's one of the problems I encountered.
You can also find extra accessories, like a special base for the phone that allows you to view the sky and planets through the phone screen.
It's definitely worth the money.
I want to emphasize here that you can easily see Saturn, although it may be small, it's easily distinguishable. However, there is a natural logical problem due to the rotation of the Earth. You can't stabilize the telescope, and you will constantly need to move it. After a while, you will lose sight of it... and you will have to keep moving the telescope. This is perfectly logical. So, here you can get a robotic system or at least another base that moves automatically according to the rotation of the Earth.
Overall, it's a great starting point for anyone
