I was taking a picture of the moon and this showed up in the photo. It may be nothing more than water. I don't know. The fact that the light seemed concentrated on one side (that facing the moon/light source) seemed unusual to me though it would make sense were it simply a drop of water.I cropped the picture because it was huge and emailed the interesting part to a friend who ran it through some enhancements and this is what turned out. I'll include the original and the enhancements. I'm fairly certain it's simply an anomaly but I figured I'd submit it regardless. Hope I'm not wasting anyone's time.
