Description

[From Wikipedia] The Heart Nebula (also known as the Running dog nebula, IC 1805, Sharpless 2-190) is an emission nebula, 7500 [url=mw-redirect=https://en.wikipedia.org/wiki/Light_years]light years[/url] away from Earth and located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. It displays glowing ionized hydrogen gas and darker dust lanes.

This is a capture of the Heart Nebula as seen from my Bortle-5 backyard a couple of nights ago. I used an Optolong L-Enhance filter with an astromodded Nikon D5300. Postprocessed with Siril 1.2.0.
