Trifid Nebula (M20)


This image was taken from my deck in Abbotsford on July 15, 2013.  It consists of 8 10-minute images registered and combined in CCDStack and processed in Photoshop CS5.

The Trifid Nebula is in Sagittarius 5,000 light years away.  It gets its name from its three-lobed appearance, and contains both red emission from ionized hydrogen and blue reflection of star light from dust grains.
