The
California Nebula (
NGC 1499) is an emission
nebula located in the constellation
Perseus. It is so named because it appears to resemble the outline of the
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 years from
Earth.
The California Nebula was discovered by
E. E. Barnard in 1884.
