|The planetary nebula M97 ("Owl nebula") in the constellation Ursa Major on
March 3/4, 2013. The Owl nebula's distance to Earth is uncertain. Depending on the source, numbers range from 400 to 12'000 light years.
M97 was discovered by Pierre Méchain in 1781. Below M97, a fuzzy object can be detected. It is the galaxy PGC 34279, partly eclipsed by a foreground star.
Eighteen 3 minute exposures at ISO 800 were added for this shot with the DeepSkyStacker software (resulting in a 55 minute exposure) and the final image processing was done in Photoshop.
