Thanks, Mike.

That would be awesome if it were the atmosphere, but in fact it's just an 
artifact.created by trying to align a moving planet while recording the blue 
channel at 8 frames per second.  The Barlow lens brings the focal length to 
nearly 10 meters, which sounds great until you realize that's f/40 in a 10-inch 
scope.  More aperture is required.
