NGC 1499 -
The California Nebula gets its name from its resemblance to the USA's most populous state and is located 1000 light-years from the solar system. It is believed to be illuminated by the star Xi Persei, the 4th-magnitude star at the bottom right of the image. Although large in size, the California Nebula has a low surface brightness which makes it difficult to detect visually. Using an H-Beta filter is helpful when attempting to see it.
