Rummaged through Cookies computer last night. The image behind the mule deer was :
May 5 2012 at about 21:30.
Canon 100-400 at 400
ISO 100
F 5.6
1/250 sec
Handheld, but leaning on a rig

Not near the clarity of Pam's though.

The mule deer buck/doe were actually snapped in overcast daylight, converted to black and white, darkened, and the night sky and moon pasted in behind the foreground and sky lined buck. The doe is in the lower left foreground and is visible if one expands the image via the "reply" button. Most effort, however, went into manually filling the small daylight sky voids in the weeds and sagebrush where Photoshop could not handle the conversions.
