 The northernmost of the Messier Trio of M36, M37, and M38, this moderately rich open cluster beams at 6.4 magnitude and spans 21 arcminutes in width. While the galactic obscuration tends to redden the faint stars in this field, some of the blue light from the dozens of blue super giants forms a base skeleton for this object, with a sprinkling of over a dozen orange K super giants on top. Visually, you can see curving chains and branches in this object, some of that can be imagined here in this image.
