With the StarSense Explorer – the first telescope that uses your smartphone to analyze the sky and calculate its orientation in real-time – Celestron redefines the manual telescope. The StarSense Explorer is ideal for beginner amateur astronomers, as the app is user-friendly and features detailed tutorial material. You'll feel like you have your own personal guide to the night sky.
When you open the packaging of your new StarSense Explorer DX, you will find:
Forget complicated star charts, inaccurate planetarium-type 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 the telescope, you'll be navigating the sky with confidence.
Place your smartphone in the special holder 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 generates a list of celestial objects that are visible (above the horizon) at that moment. Once you select the object you want, arrows appear on the screen, showing you where to point the telescope. When the object is ready for observation, the reticle turns green.
This is an extremely stable altazimuth mount, providing a solid base for the Explorer DX optical tube.
An altazimuth mount is the simplest type of telescope mount. Its name is a combination of the words "altitude" and "azimuth". This type of mount moves up and down (in altitude) and left and right (in azimuth).
By releasing the axis brakes, you can roughly point the tube towards the target, and then the fine adjustment controls on both axes help you bring it to the center of the field of view. As celestial objects shift in the sky (in reality, it is the Earth that is rotating), you can track them by turning these controls. The mount sits on a tripod with adjustable height.
With a 102 mm objective lens, this telescope has a large enough light-gathering capacity to reveal impressive details of celestial objects. You can expect sharp and bright images of the four Galilean moons, the cloud belts and the Great Red Spot of Jupiter, the moons of Saturn, the trapezium of the Orion Nebula, and the beautiful Pleiades star cluster. Celestron's XLT coatings enhance optical transmission and thus further upgrade image quality. The telescope also features a 90-degree erect image diagonal, which you can use during the day for observing birds, wildlife, landscapes, etc.
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 a few more of the most 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 4-inch refractor telescope under a relatively dark sky, the Andromeda galaxy, the open star cluster of Hercules, and many other sights will be at your disposal.

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.
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.
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!!
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
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
