Description

I did this in two turns, one for the colour shots to match a different image scale and this one where I took only the luminance shots. The first time, after all was said and done, I realised the subject needed more oomph, that is a greater image scale. After all this is THE premiere SR this side of the Orion Belt! Misjudged, in hindsight, the amount of exposure needed ay f/10 so noise is lurking in the shadows. Realised that too late, when the window of opportunity (good seeing) had passed. Reprocessed the luminance in PI.
