The Lion Nebula Sh2-132 is a weak emission nebula near the constellations of Cepheus and Lacerta. It’s thought to be between 10,000 and 12,000 light years away.
The main components of this emission nebula are hydrogen and oxygen gases, which are stimulated to a high energy state by ultra violet light from nearby stars and subsequently re-emit the light. The darker areas are “dark nebulae,” which are dust clouds that obscure light.
This image is a combination of narrowband wavelengths of light. A colour palette known as SHO (SII, Ha, OIII). The reddish areas are Ha and SII emissions and the blue is OIII.
I was happy to be informed that this image was selected as Picture of the Day by Astronomy Magazine for April 1, 2022.

My story began more than 40 years ago looking up at the Moon with a small collapsible telescope my Father had. Encouraged by my parents, who bought me my very own telescope, a 4.5″ reflector, I began to explore the night sky from my family home backyard. Today I do astrophotography from my home in Kitchener, Ontario and also with remote telescopes located in New Mexico and Australia. Some of my images have won awards and have been featured online and in magazines.
