Description

There's a lot going on here, but I was mainly looking to feature the Jellyfish Nebula, a supernova remnant and its position in a busy neighborhood. This one was done with my Redcat 51, a one-shot camera and an Optolong L-Ultimate filter. In processing I tried to bring out the blue oxygen III emissions but they are pretty weak relative to the red hydrogen alpha signal.

I shot this the same night I finished imaging a much closer view of Jellyfish, shot with my AstroTech 130 'scope in narrowband SHO. You'll find that image nearby in my library.
