Description:
Actually the first real evening where the comet seamed impressive with the naked eye and binos. Capturing the comet the night prior with the same setup and 1 second subs rendered the image of the comet useless. The bright twilight skies proved problematic. A little over 3 minutes of 21 x 10 seconds were stacked here. The unsharpened background mountain ridge of the Eastern Sierras was transposed directly from the 10 sec reference frame used to center the comet. (see Included image.) Color calibration was made using SPCC. I saturated the stars to bring out their color HOWEVER I did NOT adjust the saturation of the comet. The reddish brown vibrancy of the comet is the sole product of gradient removal, stacking & stretching! Orbital plane crossing occurred between Oct14 &15.
