The Lion Nebula

[crimbfighter]

The Lion Nebula! Imaged last night from my Bortle 5/6 back yard. This target was too large to comfortablely fit in a single frame, so this is a two panel mosaic (panorama). The Lion Nebula, also known as Sharpless 132, is in the constellation Cepheus. The red color is the ionized hydrogen gas and the light blue color is ionized oxygen.
