Messier 53 is a globular cluster located in constellation Coma Berenices. This cluster is quite far from galactic center of the Milky Way (60 000 light-year), which makes it to be located on the outer edge of our galaxy. However, it heading towards the center with speed approximately 63 km/s. The cluster contains 500 000 stars, but this cannot be verified by the photo I took, because it is 58 000 light-year from Earth and my telescope has very small aperture to resolve this kind of details.
