Pencil Nebula Glows on Deep-Space Canvas

Martin Pugh took this image of the Pencil Nebula, or NGC 2736, from his home in Yass, New South Wales, Australia over the course of two weeks in March, 2013.

Pugh used a Takahashi FSQ106N telescope with a Paramount ME Software Bisque mount, SBIG STF8300/FW8300-8 Baader 36mm filters, and Maxim DL as well as CCDAutopilot software to capture the photo. 

He processed the image with Maxim DL/CCD, Photoshop CS, CCDStack and PixInsight. The total exposure time was 10 hours.

The thin, woven filaments in this beautiful image resemble an artist’s etching into a canvas of glowing gas.

The Pencil Nebula is located 800 light-years away and is five light-years long. The nebula, named for its elongated appearance, is an interstellar shockwave seen nearly edge-on.

The shockwave travels through space at an astonishing 310,685 mph (500,000 km/h).

Scientists say the nebula is part of the larger Vela supernova remnant that produced the initial shockwave. In the image, the red and blue regions mark the glow from hydrogen and oxygen atoms.
