What A Difference A Day Makes!

Twenty four little hours...  And so the song goes...  I looked out this evening and the sky had changed dramatically since last night.  The moon, so tough to make out deep in twilight last night, is now much higher than Venus, which was the higher of the two last night and is quickly heading towards the sun, passing between us and our nearest star a week from Saturday.  So, of course, I had to document the new and revised evening view, first, the wide field view with a normal zoom lens (set to 65mm, .5 second, F/6.3) against my neighbor's palm tree and saguaros, then another showing the now-much-easier to see moon.  The "dark side" of the moon is lit up by earthshine, because when the moon is skinny, the Earth (from the moon's perspective) is full, and even a moderate exposure (1 second with Meade 80mm F/6) shows this light from Earth.  While to many the sky is unchanging, the last 24 hours proves this is definitely not so!
