M55, A Globular Cluster, - this image cropped and reduced from the original photo, Click on photo above for a full frame full rez image. |
M55 is quite a large globular cluster, about 19', roughly 2/3 of the Moon's apparent diameter, but has such a loose appearance, that in 7x50 binoculars, it could be mistaken for an open cluster: It is about 17,300 light years distant, about half the distance to our galaxies center. At this distance and at 19', it would have an actual diameter of about 100 light years. It gives off the light of about 100,000 suns. It can be found low in the sky off to the left of the Teapot. Its low height is what makes it so reddish |
