3. CLUSTER STRUCK
The constellation Cassiopeia contains
many open clusters, bright and faint.
Stock 6 is the one at the center of this
image. It’s one of 24 open clusters
recorded by German astronomer
Jürgen Stock in the 1950s. NGC 688 is
the brighter open cluster below center,
and Berkeley 63 is the tight open
cluster to its right. • Dan Crowson
4. BARK AT THE MOON
Features on the waning crescent
Moon appear sharp on the morning
of November 15, 2017. The Moon’s
illuminated portion was less than
10 percent when this image was
taken from San Carlos, Brazil.

5. BLUE GHOST
Imagers seldom capture reflection
nebula IC 2169 as a separate object
because it lies in the general region
of the much more photogenic Cone
Nebula (NGC 2264) in the constellation
Monoceros. This intensely blue cloud
scatters light from nearby stars and
reflects it in our direction.

6. THE FISH HEAD NEBULA
IC 1795 is a star-forming region
some 6,000 light-years away in the
constellation Cassiopeia the Queen.
This area is filled with a mixture of
emission, reflection, and dark nebulae.
Here, the photographer captured
the cloud through Hydrogen-alpha,
Oxygen-III, and Sulfur-II filters.
