Sh2-112 by Rod Pommier

Submitted by Chelsea Chin

Sh2-112 is an emission nebula in Cygnus lying at a distance of 5,600 light-years. It is a blister nebula on the edge of an enormous molecular hydrogen cloud and hydrogen-alpha nebulosity can be seen all around it. It is illuminated by the star BD+45 3216, the bright star near the center of the image. It is a blue supergiant of 30 solar masses. This bright nebula is just a bit north of the well-known North America and Pelican Nebulae, but sadly is rarely imaged.
