NGC 5053 is a sparse, relatively low-mass globular cluster in Coma Berenices.It is considered one of the most medal-poor globulars in our galaxy. It is chemically more similar to the Sagittarius Dwarf Spheroidal Galaxy than the Milky Way halo, leading some to believe that it was stripped from the dwarf galaxy. It is about 57,000 light years away.

I shot this in back 2019. I didn't have a lot of signal, and the first quarter moon led to a noisy image. I had started to process it, but somehow forgot about it, and only recently discovered my mistake. I now refer to it as The Lost Cluster.
