Description

From Deep Sky West freebees 3 Greyscale data download files labelled L_8x60, L_8x120 & L_13x600 were processed. These were merged using Adobe cc HDR merge and some made up ISO/Focal data. I then separated out stars from nebulosity and put the nebulosity in the red channel of a new file and the stars only in the blue and green channels. To finish (which brought back the star brilliance) I used the original merged greyscale file as a luminance layer. OK and nice so far but then did some work on the colours and balance between the areas to get this effect. False colours, yes but I was very pleased with it.
