This is the first wide field view that we are aware of that surrounds the ancient nebulae, HFG-1 (PK 136+05.1) and Abell 6 (PK 136+04.1).

HFG1 was discovered in the Milky Way Emission Line Study in 1982 by Heckathorn, Fesen and Gull (Astronomy & Astrophysics, vol.114:414, 1982). It is defined as a type F planetary nebula by Tweedy and Kitter (Astrophysical J. Suppl Series vol. 107, 1996) meaning that is appears to be uniformly filled. HFG1 was produced by its magnitude 14.5 central binary star, V664 Cas, that is precataclysmic (still detached).  The binary system consists of a white dwarf and a Sun-like star, which are only a few million kilometers apart and are orbiting each other every 14 hours.  One report suggests that V664 left a trail at least 20′ long of ~10,000-year-old shocked material as it ejected matter and moved through the interstellar medium (ISM).  It has a narrow rim approximately 14.5′ in diameter surrounding a 9′ diameter central region with an intervening gap. The rim is brightest in the south, suggesting that it interacted with the ISM. The rim is not complete and becomes too faint to be detected completely. The core has three bright lobes and a central opening nearly devoid of emission.

Abell 6, first cataloged by George Abell in 1955, is a reasonably bright but small planetary nebula at magnitude 15.0 and 3 arcminutes.  OIII is about 3 times stronger than the Ha.  Unfortunately, it is overshadowed by the more exotic HFG1.  

This was a three-person collaborative effort, with some healthy discussion/disagreement along the way, but in the end it produced what we think is an image to be proud of.  It is a very challenging area to process in that the strong Ha nebulosity has a tendency to overwhelm the OIII, and thus, much detail in the region can be swamped by the H-alpha.  Our data were collected from 4 sites:
