HFG1 is a planetary nebula in the constellation of Cassiopeia. It was produced by a binary star system (V664 Cas) that is moving rapidly through our galaxy. The star is moving towards the lower-middle of the image and a bluish bowshock is produced. A red trail of gas is left behind in its wake. The picture shows another planetary nebula towards the upper-right: Abell 6. This nebula also is emitting light in the OIII band while its intensity in the range of hydrogen is low. Abell 6 appears to be circular with a diameter of almost 3 arc minutes. Both nebula are very faint and a lot of exposure time was needed to separate them from the background.
