M46 is a gorgeous open cluster in
the constellation Puppis. In the same
line of sight — but definitely not part
of the cluster — is planetary nebula
NGC 2438. The stars in M46 lie 5,500
light-years away, while the planetary is
some 2,500 light-years closer. (3.6-inch

minutes, respectively) • Dan Crowson - UNDERWHELMING GLOB
Observers often overlook magnitude
9.5 NGC 6366 in the constellation
Ophiuchus the Serpent-bearer. It cov-
ers only as much sky as one-quarter
of the Full Moon and is so sparse that
it barely looks like a globular cluster
at all. (10-inch Astro Systeme Austria

CCD camera, LRGB image with expo-
sures of 75, 70, 60, and 50 minutes,
respectively) • Ron Brecher - TRIPLE TREAT
The crescent Moon, complete with
earthshine, passed a duo of planets
in February. Reddish Mars sits to our
satellite’s lower left while Venus shines
much brighter a bit farther away.

The Bat (NGC 6995) is one of the dens-
est parts of the eastern Veil Nebula
complex in the constellation Cygnus
the Swan. This supernova remnant has
an apparent diameter of 3°, or an area
larger than 33 Full Moons. (14-inch

minutes, respectively) • Bob Fera - IN A MIRROR DIMLY
Reflection nebula van den Bergh 106
lies in the constellation Scorpius. It
forms part of the vast nebulous com-
plex in that area and surrounds the
triple star Rho (ρ) Ophiuchi. (8-inch
