IC 443 reprocessed, better Blue channel, O-III

Nebula in natural color. Narrowband channels are mixed to match visible spectrum. Red=80% H-alpha+20% S-II, Green=O-III and Blue=80% O-III+20% H-alpha to compensate otherwise missing H-beta

Nebula in HST-palette, Red=S-II, Green=H-a and Blue=O-III

I reprocessed this closeup of the Supernova remnant, IC 443.
