LDN 858
Since classic SHO channel combinations were always a bit too "soft" for me, and those using the PixelMath formulas from The Coldest Nights *) were a bit too strong when it came to colors, I recently started not only combining the channels according to different color palettes, but also experimenting with how the different resulting images could be combined with PixelMath.
LDN 858 would now be the first result from a long series of experiments. I am still not completely happy with the formulas, but a start has been made :)
