Description

Taken from over 4 nights under Bortle 3 skies at the CalStar 2021 Star Party, this is a supernova remnant located in the constellation Cassiopeia. Even with nearly 25 hours of Ha and OIII, this was a hard object to tease out. Stars are from about 16 minutes of 20 second exposures RGB each. I used StarXTerminator for star removal on the narrowband HOO combination.
