tation to see them. Many observers report good results with
narrowband nebula filters, but that's something I haven't
tried yet with this object. From my favorite observing spots
in the Mojave Desert, the various parts of the Veil swim into
binocular visibility like seashells in the surf - delicate and
tenuous, but undeniably real. Turn to page 28 for more on
this fascinating target.
Northeast of the Veil Nebula, a wide triangle formed by
Epsilon, Zeta, and Upsilon (υ) Cygni points toward the 7thmagnitude
open cluster NGC 7063. Looking back at my old
observing notes I see that my original description of it reads
" compact, round, and evenly lit - a very nice open cluster. "
Nothing in the intervening years has changed my assessment.
If your eyes are very sharp, you may also detect what appears
to be a dark, starless band cutting northwest to southeast
between the cluster's brightest stars. Do you see it?
Northwest from NGC 7063 is the naked-eye optical
double formed by Sigma and Tau Cygni. Making a triangle
uIMPRESSIVE EXPANSE The summer Milky Way is aglow with faint
starlight, but equally prominent are the numerous dark nebulae that
bisect our home galaxy. The most conspicuous of these is the Great Rift,
which extends southward from Cygnus, through Aquila, and down into
Sagittarius.
ALMOST LOST IN SPACE The rich backdrop of the Cygnus Milky
Way makes identifying some open clusters a little tricky. However, M39
stands out better in binoculars than this photo suggests.
