Messier 22, sometimes called Great Sagittarius Cluster is a globular cluster, visually located very close to the galactic core of the Milky Way. If we look in this direction by a telescope, the surrounding of this cluster is filled with many stars. The cluster itself contains approximately 100 000 stars and it has roughly 97 light-years in diameter. The region of the sky where is this cluster located is poorly visible from my home, therefore every time I travel south with my portable telescope, I capture some deep space objects in this region. This picture was taken under the dark skies of Kythira.
