Ok, this is image is a cresent moon. I took the shot on a "bulb" setting. I manually held the camera and spun it around while focused on the moon. You will note that at a few points within the image there is what appears to be a bright crescent moon shape. This is where I paused as I rotated the camera. I took several images, and as you might imagine, no two look alike. This one came out looking like a UFO.

I've not a clue Alex. But it is a very cool capture. Can't wait to find out what it is :-). Don
