open clusters dance in this 1.5 degree wide field of view. In
the center, the primary object is M47, a rich collection of both
bright and very dim stars superimposed on a dense Milky Way field.
If it were not superimposed on the stars of our galaxy, this
object would surely rank as one of the most spectacular in the
sky. The numerous background stars tends to dillute the magnificence
of this cluster, however it is still a stunning object due to
its brilliant blue O and B stars, and hundreds of faint reddish
M47 is 4.4th magnitude,
and spans half a degree in size. Although 30 members are officially
listed in Megastar, viewing this image at a distance will reveal
a rich background glow of stars centered on the cluster. In the
upper right (South) is the smaller and more distant cluster NGC2425,
only 3.3 arc minutes ins size, 10th magnitude, and filled with
orange dim stars. Only a few extremely faint background galaxies
pepper the field, since it is within the "Zone of Avoidance"
along the Milky Way's plane.
