at 10.8th magnitude, this distant comet which lies our near Jupiters
orbit normally is a very dim 16th magnitude. Every few years
however, this comet has some sort of event, perhaps a new vent
of gas opening on the surface and brightens 5 or 6 magnitudes.
I was lucky enough to capture this current explosive venting
by staying tuned to the Comet Imaging Group on Yahoo. The comet
is primarily dust, and thus appears white in color.
Several dim galaxies
also can be seen in this field, when viewing the larger images.
A small 15.1 magnitude edge on spiral can be seen very near the
comet, just to its lower left. This galaxy is PCG26441 and is
.7 arc mins across. Another small less inclined spiral can be
seen in the upper right corner, 14.9 magnitude MCG+2-24-5. North
is up here, in this 1.5 degree wide field of view. The bright
star is 6.7 magnitude, and is an F8V class, appearing here very
white in color.
