NGC 5906 is often referred to as part of the Splinter Galaxy or Knife Edge Galaxy. It is an edge-on spiral galaxy. It is located approximately 46–55 million light-years away in the Draco constellation. It is closely associated with NGC 5907. Many, including early observers, distinguish the western part of this thin, dusty galaxy as NGC 5906. The brighter, eastern side is identified as NGC 5907.
It has an extreme edge-on orientation. Because of this, it appears as a thin sliver of light or “knife edge” in telescopes. A prominent dust lane divides it. It is a spiral galaxy with a small, compact nucleus containing a supermassive black hole. Deep imaging reveals faint, massive stellar tidal streams looping around the galaxy. These are believed to be the remnants of a dwarf galaxy absorbed about 4 billion years ago.
I photographed this from my driveway with a GSO RC8 telescope. I used an ASI071MC Pro camera cooled to 14f. The setup included a Skywatcher EQ6r Pro equatorial mount. APT controls image acquisition and session automation. 102 3 minute subs, or about 5 hours of exposure. Subframes were calibrated, debayered, aligned, integrated, and processed using PixInsight 1.9.3.
