Star Clusters

Pleiades. Canon 7D Mark II, 500mm f4

The orange star is Antares, a giant star in the constellation Scorpius. There are large interstellar dust clouds visible in the image. If Antares was placed where our sun is, it would fill the solar system out to Mars. This was with a 500mm, f4.5, ISO 1600. The two star clusters are M4 and NGC 6144.

Omega Centauri, a very large star cluster, it is about 150 light years in diameter
and contains an estimated 10 million stars, located 15,800 light years from Earth. This was imaged at a very low 5 degrees above the horizon, but looks pretty good considering that.

M 13, the Great Cluster in Hercules

M44, the Beehive Cluster. 500mm

M5, a star cluster in the constellation Serpens. M5 is about 165 light-years in diameter, estimated 24,500 light-years from Earth, and it contains more than 100,000 stars, as many as 500,000 according to some estimates. 500mm.
