M3 is a globular cluster in the Canes Venatici constellation. A globular cluster is a sphere shaped group of individual stars that cluster together. This one contains an estimated 500.000 stars.

The picture shows a clear cluster of stars with the center stars being (relatively) tightly packed. The star density decreases going outwards. More data would result in being able to see more individual stars aswell.

I enjoyed this one, fairly straightforward to process aswell!
