Urban Abell-6 and HFG-1

A fellow astrophotographer and RASC member, Kathy Walker, gave me the idea for this shot with her marathon 18 hour narrow band image of the same target. These two are dim, with Abel-6 (upper left) is listed at magnitude 15 while HFG-1 is estimated st 20. Personally I think the HFG-1 estimate is off as it seems to be both brighter and larger than Abel-6 making its integrated magnitude of 20 a little questionable.

Abell-6 and HFG-1 are two planetary nebulae in Cassiopeia. HFG-1 was formed by a binary star system (V664 Cas) that is moving rapidly through the interstellar medium creating the unique bow shock seen in the image.
