Details:
Anti-solar-tail a rich deep blue more evident on the starless versions.
Over two hours of integration time with waning crescent moon present.
Measured magnitude 10.8.
Pushed processing to show a very rich and dusty starfield.
SPCC color calibrated however I pushed the saturation showing the morphological cometary features.
Beam me up Scotty.
