M31, M33 and the Double Cluster

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.
20170130 at Sedun Observatory in Arizona.
Sky clear with fair seeing and light wind.
Canon 6D camera with 50mm Sigma 1.4 A lens on Ioptron Skytracker. This version has been cropped.
Exposure - 4 x 240s at f/2.8 and ISO 640.
Processing in ACR, photoshop and Pixinsite.
