Planetary Nebula Abell 79 in Lacerta
September 2017 - Picture of the Month
Another planetary nebula from the Capella Observatory, but this one's visible to those further north than my last selection in Norma.
Not that it'll be easy at 15th magnitude and about an arcminute in diameter. One for the large telescope or imager armed with an O-III filter. Never-the-less this image shows why it's worth having a go due to its interesting irregular shape and brightness variations.
