| Comments: |
Luminances collected in Maxim. Subs median combined in sets of three. 50 iterate PC deconvolution in CCDStack on each median. Medians averaged in Maxim, average DDPed and further deconvolved and sharpened in CCDStack Color image from previous processing: m106_st10_xcm.htm. Color image registered with new luminance in Registar, color and luminance LRGB-combined using LAB in PhotoPaint 12. New result averaged with previous result, arms boosted in PP 12. |
