Description

As the remnant of old massive stars which have since disappeared, Sharpless 2-171 is an expanding shell of gas and dust now illuminated and ionized by the high energy of the very hot new stars known as Berkeley 59 (the cluster right of center). The bright nebula illuminated by these stars is designated as Cederblad 214 (a.k.a. LBN 118.11+04.78), while the surrounding fainter diffuse nebula it is being blown into is designated as NGC 7822.

Just to the right of the Berkeley 59 stars, in the midst of the dark region of gas & dust, is the known radio source W1 (a.k.a. GRS G118.10 +05.00). SIMBAD associates Sh 2-171 with a supernova remnant, SNR G118.3+04.8. The dark cloud around Sh 2-171 is LDN 1271.
