Description

This image is the sum of 333 60 secs unguided subs taken with a Newton Orion 250 F 3.9, a QHY183M on top of a Ioptron CEM60. Filter used was Primalucelab UHC.

Aquisition with Astroart 7 (using the script the keeps the object almost in the center of the frame for the whole night), stacking, star elongation correction and deconvultion with Astroart. Layers combination, stretching, gradient removal with Astroflat pro plugin with PS.

There is a small object on the top right side of the galaxy that looks like another galaxy or a close binary star. Does anybody knows it ? I have looked on the web with no luck.

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)
