Dying Fast & Slow (Sharpless 216, 221 Region)

Image Description and Details : This is a region of space in Auriga showing a large and faint Supernova Remnant (Sh2-221) next an equally large and faint Planetary Nebula (Sh2-216). The latter is also often called the "Second Closest Planetary Nebula." The former may be an example of the earliest recorded supernova (~6600 years ago) as a cave drawing depicting this area of sky was found with a possible illustration of a bright light in the same area of sky, though this interpretation is not conclusive.

Altogether this field of view covers over a dozen times the apparent width of the Full Moon in our sky and was captured with a total of 44.5 hours across 9 nights of imaging (9 hours RGB, 36.5 hours evenly split between Hydrogen and Oxygen filters).

71mm F/4.9 Petzval Refractor, ZWO ASI6200MM-P, Antlia RGB & 3nm Ha/Oiii filters. Captured with APT and processed in PixInsight
