This image was taken over two nights from my backyard observatory. The color data was collected during a full moon, and presented some problems for processing, but it turned out pretty nice. I was working on the astrograph and rotated my camera between the sessions, so the color data does not cover the full frame, but I decided not to crop it because I like the field of view. I think the color in the central area turned out pretty good. [Description from Wikipedia] NGC 5907 is a spiral galaxy located approximately 50 million light years from Earth. It has an anomalously low metallicity and few detectable giant stars, being apparently composed almost entirely of dwarf stars. It is a member of the NGC 5866 Group. NGC 5907 has long been considered a prototypical example of a warped spiral in relative isolation. Then in 2006, an international team of astronomers announced the presence of an extended tidal stream surrounding the galaxy that challenges this picture and suggests the gravitational perturbations induced by the stream progenitor may be the cause for the warp. NGC 5907 is also known at the Knife Edge or Splinter galaxy. The galaxy was discovered in 1788 by William Herschel. Supernova 1940A was in this galaxy.
