Taken this morning at 0200 MDT with a Nikon 300mm lens on a Nikon APS-C (DX) digital single lens reflex. The moon subtended 0.533 degrees of arc. I also photographed the moon with two other lenses as part of my project to determine the focal length of the lenses. I hope to have the details up this evening. My 300mm Nikkor measured 301mm. There was, however, one surprise.
