Category: globular cluster
Globular cluster are very dense groups of stars that are in the halo of our galaxy (and probably most others also). They are very old stars, nearly as old as the Universe and their origin is still a bit o fa mystery.
Messier 13 (LRGB)
Messier 13 is one of the jewels of the northern sky. It’s a globular cluster in Hercules and if you are an amateur astronomer who has access to that part of the sky, it’s one of the first deep sky objects you saw through a telescope if that happened in the late spring through summer….
Messier 10 (RGB)
There are a lot of globular clusters out there and this one looks a lot like the typical globular. But, they make good “filler” targets because they don’t need much total time and they are still interesting. In this case, I was spending most of the night on Sharpless 112 but it didn’t get high…
Messier 5 (LRGB)
No, this isn’t a repeat of M92. We’ve shifted 87 down the Messier catalog to another globular, This time we’re in the constellation of Serpens, near the celestial equator so much farther south than M92. This cluster is about 24,500 light years away ind is about ⅔ the diameter of the full moon. It is…
Messier 92 (RGB)
This is the globular cluster in Hercules that isn’t M13. Actually to be fair, there are others but this is the only other globular in the Messier catalog that is in Hercules. This one gets a lot less attention from amateurs than its more famous cousin but it is still worth a peek. The cluster…
Messier 53 (RGB)
It’s been said that if you have seen one globular cluster you have seen them all. There’s a bit of truth to that. Some are denser and some are sparser but they generally look pretty much like this. This particular cluster, M53, is about 58,000 light years away from us in the constellation Coma Berenices….
