Full Moon shot in LRGB from home. Seeing was not great, but took advantage of a rare clear window during Christmas break.

Processing notes below:
Moon taken with ZWO ASI 1600MM Pro at -30deg C
acquired using sharpcap and stacked in AutoStakkert 3.1.4
LRGB channels captured with 10s clips

registered against L-pro channel using FFTRegister script
linearfit against red channel
pixelmath combination of registered images
unsharp mask 1.1 stddev at 60%.. 3-4 clicks
curves transformation to boost brightness and sat
color saturation to bring out reds and blues, notch yellow/greens

generate stars at RA 6:40, Dec 24:38
range mask of moon to remove stars in star field via masked histogram adjustment
rotate moon 153 deg CCW to orient back to natural position
crop rotated moon to original 1.5x pix 3948
pixelmath to combine stars and moon
