Deep Sky Nebula

The California nebula

NGC 1499 in Perseus is a large, bright emission nebula created by the bright blue star Xi Persei irradiating a hydrogen gas cloud with UV. The brightest part of the nebula spans 5 degrees on the sky and just fits on the sensor of my QHY9 when used with my Zenithstar 70 and 0.8x reducer.
