The Colors of Omega Centauri (APOD)

Featured in APOD.


I collected 165 minutes of Luminance under excellent seeing condition, from my backyard (Bortle 8 skies), and combined that data with an LRGB image from last year. Processing was done to emphasize star colors all the way to the core of the cluster.

    Magnificent! Probably my favourite deep-sky object.
    I appreciate the extra lengths to which you went to preserve its warm colour
    Despite my colour vision being affected by mild red-green confusion, I could plainly see Omega Centauri as a pearly pink heap of stardust even in a four-inch Tasco reflector as a teenager.

    Keep up the great work
