The following images are magnifications of the same original
wide field image. In this way each
object can be shown in a standard field of 3o x 3o and the
colors and magnitudes can be compared. You should be aware, that
the original image is a wide field view with a normal photographic lens! For some objects a
telescope or telephoto lens image is available.
