New moon and some clear nights :) Had to try a dark nebula again but still limited by my Bortle 5 skies. I am always so excited when I see the raw data of dark nebulae but when editing I am getting quickly down to earth again. Big trade off between noise reduction, signal and amplifying the darker parts.... Probably I need another year of practice ;)
