Here is one of the richest
areas in the entire fall/winter sky to image. Centered on NGC7635
the Bubble Nebula in Cassiopeia, the attending boxy shaped nebula
is Sharpless 2-161. The Lobster claw is to the lower right with
a very strange elongated star cluster NGC7510. Upper right is
the very bright NGC7538, and upper left is of course M52. The
number of individual Sharpless nebula in this field is astounding!
One peculiar object here is a small deep yellow reflection nebula
just to the lower right of the Bubble.
