Here's an afocal image of the Lunar X (the Werner or Purbach Cross) late in its apparition on 2010/5/20. The Lunar X is at the center of the photo. I used an 8-24mm Tele Vue zoom eyepiece, a 6" f/8 Orion SkyQuest XT6 Dob, and a Canon Powershot SD980 IS digital camera to take the shot. There were high clouds at the time and the astronomical seeing was not the best.
