    Description

    New version with a reprocess of the background and stars

    ------------
    I am happy to post this new shot composed of 2 different setups, the RGB come from my fisrt newton 10'' from the summer 2018, and the luminance from my new setup with the 12''newton .
    The 8th of October in the evening, I just started the night as usual with some SHO subs because of the moon , and it shows good FWHM, so I decided to modifiy completly my schedule and shoot this very nice galaxy, after the moonset !
    I had only time to shoot new Luminance but it was worth it ....

    From Lacerta Newton 300/1200
    56 Light subs @180s (gain 0 and -20°c )

    From Lacerta Newton 250/1000 from summer 2018
    15 Red subs @180s (gain 139 and -20°c )
    15 Green subs @180s (gain 139 and -20°c )
    15 Blue subs @180s (gain 139 and -20°c )
