November 15, 2010 - A Year-Old Rosette

A Year-Old Rosette This image of the Rosette Nebula in the constellation Monoceros was taken by amateur astrophotographer Antonio Fernandez from his home observatory in Madrid, Spain, using an 11-megapixel CCD imager mounted on a ten-inch astrograph. He obtained three sets of images totaling eight hours of exposures through Hydrogen-Alpha, Oxygen-III, and Sulfur-II filters on two separate evenings nearly a year apart. He then recombined these three monochromatic images using imaging software and assigned each to either red, green, or blue, so as to create the final full-color result. The Rosette is located at the edge of a large molecular cloud about 5,000 light-years away. It is the site of stellar birth, and radiation from the hot young stars within are sculpting the nebula’s delicate shape.
