One of the wonders of the sky is that there is so much more there than we can see with our mortal eyes. The camera helps visualize a little of this. The Eye of Heaven is seen looking down over the Golden Gate in San Francisco. It is strong and ever-present, but not at all apparent to the casual observer. Each time we are out under the night sky the Eye is up there – visible yet invisible, well known to ancient mariners who used its help for navigating, and known to a fortunate few of us who are able to visualize it in our images.
