I took a break from planetary imaging last night. This is a target of opportunity I ran across in between asteroid sets. NGC 891 is an edge-on spiral galaxy located in the constellation Andromeda. Also known as the Silver Sliver Galaxy, it was discovered by William Herschel in 1784.
There is quite a bit of detail in the prominent dust lane that evenly splits the disk. There is also another edge-on spiral galaxy apparently deep in the background slightly above NGC 891’s disk. It is very small and about half way from the central bulge and the right edge.
