About this image

HFG1 (PK 136+05) is a very old large, low-surface-brightness planetary nebula in Cassiopeia that was discovered by Heckathorn, Fesen, and Gull in 1982. It surrounds, and was produced by, a binary star system (V664 Cas) that is moving rapidly through our Galaxy. The star is moving towards the lower left of the image. As HFG1 plows through the interstellar medium, a bluish bowshock is produced; and a red trail of gas is left behind in its wake.

As ever, quite remarkable Peter. To others, you might just want to compare what the main sky surveys have 'seen' at this location - easy to access with Aladin - with what Peter is able to pick up.
