NGC 1499 – California Nebula

Yet another HII region, in Perseus this time. An emission nebula, therefore, the famous ionized hydrogen. Its name comes from its resemblance to the American state. It is 70 light-years long and is 1500 light-years away from us, making it the closest HII region to the solar system.

It’s not an easy to catch object since its best period for photograph it is the rainy season, the autumn, the month of November or December. I did it on September 3rd from 2am and it was still low on the horizon. So I kept only 80 of the 100 exposures I made.
