    Description

    mount: AP Mach1 GTO

    the light pollution gradients are killin' me, ma! had to do DBE on all the RGB subs individually, then integrate and do DBE a couple more times to really flatten the background. but i think i left some gradients in the G channel and maybe L.

    i can't remember all the nights i worked on this so i will just plug in some random dates :)

    Ha added with Vicent Peris' continuum method.
