I was really taken by the beautiful full moon in the clear night sky back on February 8, 2009. The temperatures here were above freezing for the first time in several weeks so I decided to get out the Sigma 300-800mm and try my hand at taking a few shots of the moon. Here is my favorite shot of the series, Taken with the D200 and the Sigma 300-800mm @ 750mm with the Kenko 2x teleconverter for a focal length of 1500mm @f16 1/6 sec exposure. I am quite impressed with this lens and the new Wimberley Gimbal and Gitzo tripod are rock solid performers. I actually had to back off the zoom to 750mm to get the entire moon into the frame.
