The Lion Nebula / Sh2-132

I finally got the chance for a few nights this month on this wonderful target: A beautiful, if faint, emission nebula between Cepheus and Lacerta and probably my favourite nebula to date - The very small planetary nebula (bottom left) is Abell 79. Abell 79, "The 6 Nebula", is estimated to be at a distance of 5900 to 11,360 lys away. It measures approx 1 arc minute and is magnitude 15. Sh2-132 lies at an estimated distance of about 10,000-12,000 lys and is ca. 40 arc minutes in size. The image also contains the very small planetary nebula G101.5-00.6, which lies to the right of the blue O-III region.
