|Jellyfish Nebula - IC 443
IC 443, nicknamed the Jellyfish Nebula for obvious reasons, is the remnant of a supernova explosion at least 8,000 years ago in the
direction of the constellation Gemini. Much of the light does not come from the explosion itself. Rather, the energetic shock wave from
the supernova excites hydrogen atoms within a molecular cloud, creating a lattice-like filaments of luminosity.
This image combined 60 minutes luminance exposures using a Hydrogen-alpha filter with 20 minutes of green and red and 30 minutes of
blue exposures. The Ha channel was blended into the red channel. An ST10XME camera was used through a Takahashi Sky90
refractor with reducer at my new observatory.
