the galaxy M33, north is up. the core of the galaxy is tan colored with blue spiral arms going out counterclockwise. knots of Ha are seen interspersed throughout the spiral arms.

M33 from bortle 8, last step was new denoising tool called "Prism Deep". probably best used on images that are noisier than this one but still helped a little bit. Ha added via R continuum subtraction. #pixinsight #m33 #galaxy #astrophotography #HaRGB #prismdeep #astro @kat-astro-bot.bsky.social

The Sword of Orion. M42, M43, and NGC 1977. 584 minutes HaRGB with a Celestron RASA 8, Sky-Watcher EQ6-R Pro, and ZWO ASIAir. Color data was taken with a ZWO ASI071MC camera and IDAS GNB filter (Ha, Hb, OIII + NIR). Hydrogen Alpha Luminance was taken with a ZWO ASI2600MM camera and Baader 6.5nm f/2 high speed Ha filter. Processed in DSS, GraXpert, PixInsight, and Photoshop. Taken over 3 nights from light polluted Long Beach, CA.

Every winter, I look forward to Orion rising, and with it the Orion Nebula. This is one of my deepest images yet. Almost 10 hours of imaged at f/2 from light-polluted Long Beach.
