M16 L Ha G B 2nd attempt, best images only. Lower bias for luminance frames (50%)

For this second attempt at the Eagle Nebula, I was more strict on the selection criteria of the individual sub-frames to be aligned and stacked.

During the processing stage in Maxim, I also chose a lower (50%) bias for the luminance frames, bringing out more of details captured with the Ha filter.

70x50seconds x LRGB = 3.8 hours exposure combined
