Description

This image is the sum of 156 120 secs unguided subs taken on the 27th of may with a modded Canon 600d, an Acuter 90-900ed with an AP 67 Focal Reducer, Astronomik CLS and Baader IR-CUT filter used. On top of a Newton 250 F 3.9 on top of an Ioptron CEM60EC (image from the newton is coming soon). Stacking and star elongation correction with Astroart. Background correction with Pixinsight. There is a gradient on the left part of the image, that I have not been able to remove. Usually I would have cropped that part of the image, but this time I have decided to keep it, in order to show a small galaxy which is exactly on the border, maybe galaxy is ngc5905.

NGC 5907 (also known as Knife Edge Galaxy or Splinter Galaxy) 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. 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.

The galaxy was discovered in 1788 by William Herschel. (Wikipedia)
