If our Sun were part of this star cluster, the night sky would glow like a jewel box of bright stars. This cluster, known as M53 and cataloged as NGC 5024, is one of about 250 globular clusters that survive in our Galaxy.

Most of the stars in M53 are older and redder than our Sun, but some enigmatic stars appear to be bluer and younger. These young stars might contradict the hypothesis that all the stars in M53 formed at nearly the same time. These unusual stars are known as blue stragglers and are unusually common in M53. After much debate, blue stragglers are now thought to be stars rejuvenated by fresh matter falling in from a binary star companion.

M53, visible with a binoculars towards the constellation of Bernice’s Hair (Coma Berenices), contains over 250,000 stars and is one of the furthest globulars from the center of our Galaxy and is 58000 light years away from earth.

I took this over 7.5 hours. (Luminance 30 images of 10 minutes each and took 11 images of 5 minutes each for each of the 3 colors).
