Hi, I captured this data last month and finally got around to processing it. This is a cropped version of NGC 891. You can just make out the dusty filaments in the halo. These patterns are extending into the halo of the galaxy, away from its galactic disk. Scientists presume that supernova explosions caused this interstellar dust to be thrown out of the galactic disk toward the halo http://www.azstarman.net/NGC891_CROP.htm The full frame version can be seen here http://www.azstarman.net/NGC891.htm Bernard -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
