California nebula (NGC 1499) in Perseus, an emission nebula emitting mostly at the red wavelength of hydrogen-alpha light but also with a strong hydrogen-beta emission line in the blue-green part of the spectrum. Below is the small blue reflection nebula IC 348, a cloud of dust surrounding hot blue stars and reflecting their light. The region also contains some dim red emission nebulosity. Also throughout the field are patches of yellow-brown dust that form obscuring dark nebulas. The main dark nebulas are Barnard 5 (above IC 348) and Barnard 4 below.
