One more from Monday’s narrowband imaging run. Nebula Sh2-54 is about 5000 lightyears away in the constellation Serpens. It’s part of a long band of nebulosity that extends almost ten degrees through the Eagle Nebula (M16) and Swan/Omega Nebula (M17) beyond that. NGC 6604 is the cluster of stars above and to the right of the brightest knot of the nebula. This is the final target from Monday’s imaging run. Imaging notes: William Optics GT81, ZWO ASI1600MM-Pro, Astronomik Ha 6nm filter, 30 stacked 3 minute exposures, no calibration frames. https://SaltwaterWitch.com
