This is a stack of 70 shots of 3.5 minutes each totaling about 4 hours of exposure time. Then it was processed like crazy. I used a Celestron 8" RASA scope, a CGEM II mount, a ZWO ASI294MC Pro camera. The software was Nebulosity, PHD2, Affinity Photo and Pixinsight. I was somewhere out in the Mojave desert when I shot this nebula so I only used an ir/uv filter.
