Located 25 million light-years away in the constellation Ursa Major, the Pinwheel Galaxy, with its vast regions of bright nebulosity, is roughly twice the diameter of our own Milky Way and is estimated to contain one trillion stars.⁣ A type-2 supernova, SN 2023ixf, newly discovered on May 19th, 2023 can be seen near the base of the predominant outer spiral arm of the galaxy.⁣ ⁣ We are star dust.⁣ ⁣ ——————⁣ ⁣ ⁣This image was created with data captured from May 1st - 15th using two 8” reflector telescopes and cooled, monochrome cameras with broadband and narrowband filters.⁣ A few days later on May 19th a new supernova was discovered in one of prominent spiral arms, so anxiously I waited for clear skies to go back and image one more night to capture this lucky event. Swiping left will show you before and after the supernova. ⁣ For this image I’ve blended in some Ha emission wavelength into typical L, R, G, B broadband data. I hope you like it! ⁣ ⁣ ⁣68hr 19min⁣ total exposure time⁣ ⁣ 250x 300” Ha⁣ 2793x 30” L⁣ 899x 30” R⁣ 1080x 30” G⁣ 926x 30” B⁣ ⁣ 20x Darks⁣ 100 Flats/Dark Flats⁣ 05/01-02, 05/10-11, 05/13-15, 05/23/2023⁣ Bortle 7⁣ Calgary, AB⁣ ⁣ Duplicate Setup: HaLRGB ⁣ 1624mm Focal Length⁣
