Moon Ring Over Lake Wallkill

Saw one of these in early November, and again tonight. Moon rings are caused by moonlight being refracted by ice crystals in the upper atmosphere. Photo taken handheld, Canon Digital Rebel (300D), ISO 1600, 1/2-sec exposure, 18-55mm EFS lens (@ 18mm, barely wide enough to capture the entire ring!). Had to Photoshop the hell out of the image in order to bring out the ring, thus the grainy, overexposed look.
