Sh2-216 Planetary Nebula

Sh2-216 also called LBN742 is the largest planetary nebulae in the sky, it is about 3x wider than the moon as seen from earth, although it is too faint to be seen. It is about 500000 years old, explaining why it is so very large and very dim. Sh2-216 is also the second closest planetary nebula at a distance of 400 light years. This photo was taken in December 2021 and January 2022 at my remote observatory in Jiuliancheng Town, Hebei Province, China. My equipment: SharpStar FRA 600/5.6 APO with 0.72 Reducer, ASI ZWO 6200 MM, Paramount MX mount and Astrodon LRGB and 3nm HSO filter.
