NGC1499 - California Nebula Ha Mosaic  
Perseus

Faint 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.

This picture is a mosaic of two images.
