Description

Had to reshoot the colors for this image, since I had noticed that green isn't parfocal with the others. Need to find out if it's the reducer/corrector which is causing it, or if the scope isn't as apochromatic as advertised.

EDIT: redone from masters. Integrated RGB pseudoluminance with actual Luminance and did careful NR with Atrous Wavelets and MultiscaleMedianTransform. Happy with the improvement.
