Comet C/2020 NEOWISE image shows movement over the night sky

Rick Kelly (a NJAA member during the 1970's) and member Al Ernst cooperated on this shot of Comet NEOWISE C/2020, showing it's motion over 2¾ hours. 

Al took the comet's image on the right through a blue/green filter on July 28th at 2:30UTC from his home observatory in Bridgewater, New Jersey while Rick took the unfiltered image on the left from Castro Valley, California at 5:15UTC.

It's a great comparison showing this great comet's movement over the sky during such a short period of time.

Thanks for sharing Al and Rick.
