The past two nights I was able to photograph Comet Lovejoy, despite the onsite of clouds and rain. The sky was more clear on Wedns. night, shown by the better color and contrast in the first photo.
However, I was surprised to see the last night, when photographing through clouds, the comet had a more noticeable tail.
Also more noticeable is the slight drift or elongation of stars, caused by not having my camera mount accurately polar aligned. I couldn't see Polaris, so I had to guess at the alignment, and so the stars and comet show a little drift. I wonder if the drift motion, being at a right angle to the direction of the tail, helped enhance the tail.
