Wide field refers to the fact that these images were submitted with the
Moon as a small disk with many brighter stars in the image frame. The resulting star field is large in size but
isn't good for positional accuracy.
Inter-continental these observers were thousands of kilometers apart.
Two image positions were used to create this animation. One - the base image - was from
Peter Zimmer in New York City. His image shows a number of bright stars (including the
Pleiades star cluster towards the top of the frame) and the remains of a vapour trail.
The second image was overlaid on top of Peter's image to show the effect of travelling
approximately 6,800km (4,200 miles) to the east.
