Description

NGC1499, also known as the California Nebula (it resembles the outline of this US state), is a large emission nebula with a low surface brightness, which makes it difficult to observe.
The nebula is most likely to be illuminated by Xi Persei (the brightest star in the image).

The nebula lies at a distance of about 1.000 light years, is about 100 light years long (spans about 2.5° of sky) and can be found in the constellation Perseus.
