Although sky conditions were quite different (more humidity, less transparent skies, and photographed this time after the comet passed the meridian) it's still interesting to compare Comet 17P/Holmes to the previous shot from a week ago.
This weekend's photo shows an enlarged central coma, though it seems to have lost much of the fluorescent greenish glow. The comet's blue ion tail also detached earlier in the week and can be seen floating to the right of the comet.
