NGC 2736 aka the Pencil Nebula or Herschel's Ray
NGC2736, aka the Pencil Nebula or Herschel's Ray, is a small section of the Vela Supernova Remnant approximately 800 light-years from Earth in the Southern constellation of Vela. It glows brightly due to ionised Hydrogen (red) and Oxygen (blue/green) where the shock wave from the supernova has ploughed into interstellar gas clouds. The original, violent death of the star which went supernova took place approximately 11,000 years ago.
Scope: Planewave CDK17 @ f/6.8 = 2939mm FL
