You did not post your moon images; however, you should know that shots of a full or nearly full moon are frequently disappointing. This is because the moon’s craters are ringed by mountains. At the time of the full moon, it is high noon on our nearest neighbor. That means the sun is directly overhead and the mountains cast no shadows. We need to see the shadows of the mountains on the moon, as this causes them to stand out in bold relief. It’s a fact that the moon’s surface as seen from earth is mostly a mundane white; thus we need shadows to give depth to the terrain.

Don’t be discouraged! Reshoot at first and last quarter. This is when the shadows of the mountains of the moon are long. Do use a tripod, and keep the exposure as short as possible. Also, do bracket your exposure by shooting repetitive exposures at different aperture settings. This technique insures success.
