IC 443 Jellyfish Nebula in HALRGB
A supernova remnant some 5000 light years out in space. As with the Cygnus Loop you can envision the central point where the star must have exploded pushing out the gas and dust; now many thousands of years later some parts of the shell are brighter than others and form this interesting jellyfish shape. Unlike Cygnus/the Veil what we can see here is almost all hydrogen/red. For this version I added two hours of HA narrowband capture, improving the contrast and detail of the nebula.
Tech Stuff: TV-85/Borg 1.08X Flattener/Star Adventurer Mount unguided
3 Hours ZWO ASI1600 MC/IDAS LPS-V4 filter/
2 hours QHY163mono/Astronomik HA filter/
4 and 8 second exposures captured as livestacks in SharpCap/ Processed with PixInsight/GIMP/ACDSee.
From my yard 10 miles north of New York City, SQM-L reading 18.5-18.8 (Bortle 7).
