Description

NGC7288 in SHO (SH2-171 and SH2-172). This is also called CED214. The combination of the two nebula looked like a question mark to me.

Sh2-171, as designated in the Sharpless Catalog of HII emission nebulae, is a star forming complex located in the constellation Cepheus at an approximate distance of 3,000 light years from the Earth. A very young cluster of stars, designated Berkeley 59, is located in the upper center right of the image. The cluster is only a few million years old and is the primary ionizing source of illumination for the nebula. Its intense radiation and strong stellar winds have shaped and eroded the many columns and pillars seen in this remarkable star forming complex. The Berkeley 59 cluster contains one of the hottest stars within a thousand parsecs from the Sun. It is an eclipsing binary containing an O5V star (BD+66 1673) with a surface temperature of almost 45,000 Kelvin. It has luminosity approximately 100 thousand times that of our Sun. The bright star located in the center of the image (SAO 10956) is not associated with Sh2-171. It is a foreground star approximately 317 light years from the Earth.
