Sh2-271 appears to be the brightness HII region at the center of the image. Simbad shows this one further left (east). This one is approximately 12,700 light-years away in Orion.

Sh2-272 is the smaller HII region located approximately 16,200 light-years away. Like Sh2-271 above, this was also first suspected to be a planetary nebula.
