The '''California Nebula''' ([[New General Catalogue|NGC]] 1499) is an emission [[nebula]] located in the constellation [[Perseus (constellation)|Perseus]]. It is so named because it appears to resemble the outline of the [[United States|US]] State of [[California]] on long exposure photographs. It is almost 2.5° long on the sky and, because of its very low [[surface brightness]], it is extremely difficult to observe visually. It can be observed with a H-Beta filter (isolates the H-Beta line at 486 nm) in a rich-field telescope under dark skies. It lies at a distance of about 1,000 [[light year]]s from [[Earth]].
The California Nebula was discovered by [[Edward Emerson Barnard|E. E. Barnard]] in [[1884]].
