SH2-71 , SH2-72, and NGC 6749
This image is of a region within the Milky Way in the Constellation Aquila where one can find a dim Hydrogen Alpha nebula called Sh2-72. In the image, Sh2-72 is the large reddish cloud just right of center. This area of the Milky Way is very dusty and also includes several other objects. A globular cluster called NGC 6749, the orange star cluster in the lower right part of the image, has its color reddened by the dust it has to shine through. Near the upper right is a planetary nebula PK 36-1.1 which is the remnants of a star which ended its life by shedding its gas. This gas glows red in this image. This image is a combination of 12 1/2 hrs of exposure time through Luminance, Hydrogen Alpha and RGB filters.
