Description

Abell 6 (PK 136 +04.1) is a typical faint bubble-like planetary nebula on the left. Both lie in Cassiopeia.

HFG1 (Heckathorn-Fesen-Gull 1) is a larger and older planetary nebula first uncovered in 1982. The interesting thing of this nebula is that it shows a leading edge shock wave ahead of the bubble as it plows through the interstellar dust. Even deeper images in Ha wavelengths actually show a comet-like tail. I barely could detect that in my Ha stack if I stretched it a lot.

Subs: 16x5min CLS (luminance), 20x1min Hb, 22x5min Ha, and 36x5min O3. 6.5 hours total exposure over 3 nights at LLCC. At least 2 hours of subs were thrown out due to the variable sky and windy conditions.
