Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission. This composition is very close to a visual spectrum.



NGC 1499, the "California Nebula" locates in constellation Perseus. Distance is about 1000 light years.



The nebula covers about 2,5 degrees of sky. RA 04h 03m 18.00s Dec +36° 25′ 18.0"



I did reprocessed this nebula since my skills are much better now, than two years ago.

All the exposures I have taken for this object are used. Total exposure time is now about 20h together.



Two camera lenses was used to capture the data, a Tokina AT 300mm f2.8 and a Canon EF 200mm f1.8, both lenses was used at full aperture.
