Description

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.


The new series of telescopes Celestron StarSense Explorer introduces a new way of observing the night sky. It is a true revolution. Until now, Celestron offered two types of altazimuth telescopes: manual and automated NexStar+. But now the StarSense Explorer series offers amateur astronomers a new way to observe the starry sky.

Forget complicated star charts, inaccurate planetarium-type apps, and expensive automated mounts. With the Celestron StarSense Explorer telescopes, finding celestial objects is easier and faster than ever before.

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 a few minutes, you will have all the sights of the night sky at your disposal. Select the object you want from those above the horizon at that time and simply follow the instructions on your smartphone screen, so that by properly adjusting your telescope, you can center that celestial object, whether it's the Moon, a planet, a galaxy, or a nebula. Then, just look through the eyepiece.

Unlike all systems available on the market, including astronomical applications, the patented Starsense Explorer system automatically recognizes the exact orientation of the telescope in the sky with the help of the brightest stars.

How does object tracking work?

Select the object you want to observe from the list suggested by the StarSense Explorer app. The app will show you where to manually point the telescope. Point the telescope following the instructions. Center the object. Now you can start observing.

Compatible with most smartphones on the market

The Celestron StarSense Explorer is compatible with most smartphones on the market. You simply follow the instructions on your smartphone screen to enjoy some of the most beautiful objects in the night sky. Even if you are observing from an urban center, you will have access to many of these objects, including planets and the Moon, the Andromeda galaxy, the Orion nebula, star clusters, and many more.

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 review is about the lens diameter: 165.1 mm

    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!!

    This review is about the lens diameter: 165.1 mm

    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
