The tail of the Scorpion...
The scene in this photograph is dominated by three stars from the constellation Scorpio and two large open clusters.
The two bright stars from the center of the image to the left are Sahula (Lambda Scorpii) and Lesath (Upsilon Scorpii), which form the scorpion's stinger. Above left is the variable star Kappa Scorpii. These beautiful stars are among the brightest and are very easily seen with the naked eye in rural skies, offering a magnificent view that sets the end of the scorpion.
From the center of the image upwards, you will see a large open star cluster, Messier 7, very easy to distinguish with the naked eye from a dark sky. It has more than 80 stars and is sometimes known as the Ptolemy Cluster.
From the center to the right, another cluster is present in such a vast field of stars. It is Messier 6, also known as the Butterfly Cluster and is made up of more than a hundred stars.
Other treasures of the night appear timidly in this photograph, such as the globular cluster NGC 6441, attached to the star G Scorpii, which to the left of M7 is seen as two yellow-orange stars.
On the intermediate path from Shaula to G Scorpii, you will see another small cluster, NGC 6400. But there are many other treasures hidden in this photograph... Do you dare to find them?
