M7, aka Ptolemy's cluster (LRGB)
The M7 Open Star Cluster in southern constellation Scorpius, looks suspended above billions of yellow grains of sand. The background, yellow stars in the bulge of the Milky Way, make M7 look like a collection of blue sapphires surrounding one brilliant orange gem. Pre and Post processed in Pixinsight, using a custom LRGB workflow. The challenge of keeping background darkness without any color leak was worth the effort!
