Sh-132 The Lion Nebula. SHO

Sharpless 132 or The Lion Nebula, is a faint emission nebula located near the border of the constellations of Cepheus and Lacerta. It lies at a distance of between 10,000 and 12,000 light years.

Had to work hard to bring out the SII and OIII detail in this one. Do not get enough clear nights to spend any more than 4 on a single image.

Imaged over 4 nights, 2 in April 2022 and 2 in August 2023.
