Barnard's Loop
City dwellers learn to spot Orion by the three bright stars forming his belt, and M42 in the sword is a popular target for small telescopes. But we never see the other vivid nebular areas which are revealed by long exposures. And it's easy to overlook these really large structures when learning astrophotography. Once I had my camera lens configured with my astrocam, I wanted to try this shot of the wide semicircular emission nebula around the belt and sword. Once again, the IDAS LPS-V4 filter brings out not only the nebular regions but also a surprising star field from my "red zone" suburban yard.
Tech Stuff: Canon 17-55mm f2.8 zoom lens/ZWO ASI1600MC cam/IDAS LPS-V4 filter/iOptron CubePro 8200 mount unguided/70 minutes total exposure time using 8 second exposures captured with SharpCap Pro/processed with PixInsight and GIMP. SQM-L reading 18.9. From my yard 10 miles north of New York City January 6, 2019.
