California Nebula
The California Nebula is a prominent target in the autumn sky. Invisible to backyard observers with small telescopes, the Hydrogen-alpha light emission makes it easy to reveal with filtered astro-photography. Here I am experimenting with the popular trend of using "Hubble Palette" coloration which was necessitated by the need to assign visible colors to energy -- like UV and infrared -- outside the visible light spectrum. With my backyard data from the NY suburbs, the transformation from the familiar "lobster claw" appearance displays more complexity in this great cloud of galactic dust.

Starting March 7th, I'll be teaching a fresh round of Urban Astrophotography: Deep Sky with NYC's Amateur Astronomers Association
aaa.org/event/urban-astrophotography-deep-space-imaging-2...
The six Zoom sessions are available to members and non-members for a slightly higher registration fee.
Tech Stuff: Borg 55FL/ZWOASI533MC/IDAS LPS-V4/RST-135E. 6 Hours of unguided 8-second exposures captured in SharpCap Livestacks, processed in PixInsight. Imaged over 2 nights in November 2023 from my Bortle 7 yard in Westchester County.
