Description

California Nebula (NGC-1499). Red everywhere. I observed a weak signal for OIII from this nebula even after 5 hours of imaging. Perhaps due to the full moon? or this nebula has weak OIII emissions. Therefore, the principal contribution is coming from H-alpha and SII data. It's challenging to subdue the reds of H-alpha. For star colors, I had separate blocks with broadband RGB filters.
