Grus Triplet: NGC 7582; 7590 and 7599
This trio of galaxies is known as the Grus Triplet. They include NGC 7582, 7590, 7599, and are about 60 million light-years away. Whenever I finish processing an object, I love to look around to see if something interesting is in the field. My eye was drawn to the clusters of galaxies along the top of the frame. At first, they may appear as stars, but you can see groups of galaxies if you look closely. The semi-circular ring of galaxies near the top and slightly right of centre is so cool. It has kind of a golden colour. These are all galaxies. If you scan to the left near the top, you will find more clusters of galaxies. In fact, there are hundreds of galaxies in this frame with many over a billion light-years away.
Exploring all these wonderful gems would have to be one of the main reasons I enjoy photographing deep-sky objects. Researching these distant objects, their learning about their compositions s rewarding. The fact that we can image galaxies that far back in time with modest equipment is nothing short of incredible.
