Comet
177p Barnard - August 2nd
8th
magnitude comet in Hercules
Uploaded
10/4/06
This 8th magnitude
comet is currently near its peak brightness, and will start to
fade in the coming weeks. A very strong cyan coloration dominates
this object, the Swan emission bands are strong here. Only a
hint of a tail is seen as a greenish brightening just below the
comet, best seen in the smaller images such as above due to being
a very low surface brightness. The comet is currently very easy
to find, being within the "Keystone" asterism of the
constellation of Hercules.
Processing:
30 RGB images combined in Maxim DL, with Photoshop CS2 used for
final brightness and contrasts.
