M53 - GLOBULAR CLUSTER in COMA BERENICES
|
About this Object: |
|
One of the more richly colored globular clusters in the night sky, M53 is moderate sized cluster in Coma Berenices, a constellation mostly known for it's galaxies. M53 is one of the more distant globulars from the galactic center, around 60,000 light years out and 58,000 light years from us. It is more loosely packed than many globular clusters, rating a Class V on the Harlow Shapley scale. Viewing this object isn't difficult. Small telescopes and binoculars will show M53 as a "faint fuzzy" in dark skies. Telescopes 8" in aperture and upwards will show the core stars resolved as individual point of light. It'll take on a slightly oval shape overall, with its light falling off uniformly from the center. A really nice object indeed! |
