Orion Region H-alpha
Another take on Orion, Barnard's Loop and the Rosette using an H-alpha filter to emphasize the hydrogen clouds through the region. Narrowband filters block most wavelengths including light pollution from the city and the moon. I added an hour of data to four hour's worth collected last year and made different processing choices for this version.
Tech Stuff: Canon 17-55 f/2.8 lens at 35mm on QHY163 mono cooled astro camera with Astronomik H-alpha filter, unguided tracking via iOptron CubePro mount. 330 minutes of 8 second exposures captured in LiveStacks via SharpCap; processed in PixInsight. Captured over 4 nights, November 2020-January 2021 from my yard 10 miles north of New York City.
