IC 443 reprocessed, Closeup and wide field





Since my processing technique gets better and weather doesn't give any support, I have reprocessed couple of older images. There is now star colors added and other processing is tweaked too.


IC 443, wide field



Image is in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.


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. 
Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.

Original version with technical details:
(Shot with a Tokina AT 300mm f2.8 lens and QHY9 astro camera)
