M53 and NGC 5053 - Two very different globular
clusters.
The two globular clusters in this image are
very different, while M53 shines at magnitude 7.7, NGC 5053
has only 9.5 mag and is not visible in small telescopes. Despite
the very different apperance they are both at about 55000
light years away. That means that they are also very different
in physical nature, NGC 5053 is much sparser than a typical
globular cluster.
