Arp 286 (NGC 5566, NGC 5569, & NGC 5560)

Arp 286 is made up of three interacting galaxies, NGC 5560, NGC 5566, and NGC 5569 located approximately 80 million light-years away in the constellation Virgo. NGC 5566 is a barred spiral galaxy and the largest of the trio at 150,000 light-years in diameter. It has a very distinct dust lane on the upper portion and to travel with one of the broad arms. This galaxy has a yellow tint while its closest and smallest neighbor, NGC 5569, has blue tint. NGC 5560 has a yellow core and blue outer portion.

I imaged this about a month ago while it was in a good location for me. I found this object while searching Stellarium and ironically I saw that Michael Feigenbaum had just posted a fabulous version of this object. I am happy with how my version turned out although there is not as much detail as I had seen on other versions. I only collected RGB data but wish I would have collected some Hydrogen. Also, this happens to correspond to when the Alberta smoke began to affect our skies so my next few images may be iffy.

M53 & NGC5053 (2023)

M53 (also known as NGC 5024) is a globular cluster located in the constellation of Coma Berenices. It is approximately 60,000 light-years away from us and ironically the same distance away from the center of the Milky Way. The metal poor cluster is dominated by blue and yellow stars. Metal-poor clusters are composed mostly of first generation stars (stars that are still burning their original light elements such as hydrogen and helium). The other feature in this image is NGC 5023, also a metal-poor globular cluster but much more diffuse. It is very close to M53 and is believed to have interacted with it in the past.

The other stars in this field of view are quite colorful. Located in the upper right corner is the very far spiral galaxy IC 857 along with some other interacting galaxies (IC 858 and IC 859) just below.

I find processing globular clusters particularly difficult but they are fun to do anyway. Capturing this object was pretty interesting as the sky conditions have been particularly iffy due to Canadian wildfires. First there were the Alberta fires which were affecting the transparency when some of this data was collected so I had to trash some of the data. Most recently we have been dealing with actual smoke from much closer wildfires in Quebec - the smell is pretty bad but the red sun at noon looks pretty cool.
