Description

Stars settled a bit as comet 13P/Olbers appeared to show more activity than the prior postings.  The comet started the imaging session at 16 degrees altitude, in late twilight, when a dark cumulus cloud entered the scene.  I managed to save 27 of the 58 x 30 second exposures for this stacked image.  The sky conditions otherwise  were good allowing for a more colorful cometary appearance.    Also noted near the comet's brightened pseudo nucleus is a "V" shape detachment as well as many more streamers/ jets of increased activity. 

Please excuse the roughness of the image since I am dealing with less than 14 minutes of data.  The crescent moon was less than 3.5 degrees away from the comet.
