Since there's a few hours of darkness now before Moonrise, the
ones taken in the early evening are excellent. An interesting
comparison is the shift is sky appearance (and relative star
brightness) between the red and blue filter images. For instance
in the evening now the Square of Pegasus is easy to pick out in
the blue image, but lost in the red image because of the strong
colors of the stars making up the square. The images go deep enough
in surface brightness to show the zodiacal band and gegenschein
in the blue image, and the rippling pattern of the night airglow
in the red images (see the link to the animations).
