M31, M33 and the Double Cluster
This is a 2021 reprocessed version of image 816, a wide field image taken with a 50mm camera lens contains three treasures that are usually imaged separately with much higher magnification. They are M31, M33 and the double cluster. I like seeing them at a scale that is similar to the field of view of our eyes.
