Two Comets Pass by The Dusty Pleiades and the Fiery California Nebula

Comet C/2017 O1 ASAS-SN, the green dot center bottom right, and Comet C/2015 ER61 PanSTARRS the up and down white dusty streak just below and to the right of the blue Pleiades pass through this colorful area of the constellation Perseus. The next image in my feed contains labels and orbital overlays of the comets.
