Description

This is one of my favorite targets in the night sky.  Lots of hours on this one and I'll be making different color combinations.  Imagined over multiple nights from my backyard in Snoqualmie.  Processed in PixInsight.   Sharpless 2-188 (Sh2-188) is an unusual planetary nebula located in the constellation Cassiopeia. The expanding gas from the planetary nebula is colliding with ambient gas in the interstellar medium. The nebula is nearly circular in shape but is much brighter to the southeast (lower left) because the central star is moving rapidly in that direction. Faint wisps of gas can also be seen in the opposite direction.  (courtesy: https://noirlab.edu/public/images/noao-sh2-188/)
