This is a older series which I re-processed using some new capabilities I added to SBG recently. SBG now includes lossless processing of stacked images. Because image stacking increases the bit-depth of the resulting image, more severe manipulation of the tone curve / levels and other histogram magic. The 5 image stacking produces 10-bit / channel images. We take advantage of that to normallize the histogram and then stretch the histogram to rediculous proportions to make an otherwise boring sunset into something more, well, thermonuclear.
