The star field around NGC891

Image 1: The galaxy NGC891

NGC 891 (also known as Caldwell 23) is an edge-on unbarred spiral galaxy (actually barred) about 30 million light-years away in the constellation Andromeda. [1]

Image 2: Galaxy groups near to NGC891

No kidding. This shot is a really deep one! Watch the many galaxies out there! NGC 898, NGC914, NGC906, NGC909, NGC911, NGC910, NGC912, NGC913 and numerous other faint PGC galaxies are visible!
