Supernova remnant in the constellation Cassiopeia. Resized to 1440 pixels on the short side — not enough signal, will need to gather more data when possible. Processing artifacts and star reduction are already visible. There’s also a bit of oxygen in the nebula, but that would require about 20 hours of exposure, definitely not happening this year.
