Title

Heavily populated area of the Milky Way in the constellation Serpens Cauda. I don't have much faith in the SPCC color calibration. Mixed sky conditions with partly cloudy skies. I wasn't going to image, but at the last minute thought "Why not"? The brightest blue star left of the field is an interesting dual spectral class A double star named Alya. These two stars , magnitude 4.62 and 4.98 are separated by 22". Look close.
