    Description

    Sometimes you get it so good that you have to post it as new! :) Jokes aside, I worked again a lot on the raw files of this picture retaking darks to stack them properly for the ASI1600MM-Cool and calibrating all the frames again. This finally removed the amp glow noise that was plaguing the image. And I am happy to say that I finally understood how the Hubble palette works, sometimes you find that tip that changes everything... and now I have to revamp all my SHO pictures :)
    And too bad for that halo on the brightest star... the culprit is a reflection of the OIII filter caused by the Moon (I guess).
