Quote This was the longest exposure for this night and we managed to capture both the owl nebula (M97) and the surfboard galaxy (M108). Both objects came out pretty nicely. See more information here for the night this picture was taken. Quote

FactsA planetary nebula is a kind of emission nebula consisting of an expanding glowing shell of ionized gas ejected from old red giant stars late in their lives. The word 'nebula' is Latin for mist or cloud and the term 'planetary nebula' is a misnomer that originated in the 1780s with astronomer William Herschel because when viewed through his telescope, these objects appeared to him to be newly forming planetary systems. Herschel's name for these objects was adopted by astronomers and has not been changed. They are a relatively short-lived phenomenon, lasting a few tens of thousands of years, compared to a typical stellar lifetime of several billion years.Factssource and more information wikipedia
