North is up in this image. This field is the LBN 468 Region in the constellations of Cepheus and Draco (on the border). This is a region of dusty interstellar matter  with some star formation. In the upper left corner is a small nebula illuminated by a protostar. The nebula is  GM 1-29 also known as Gyulbudaghian's Nebula. The protostar is the variable PV Cep. LBN 468 is the large structure dominant in the image. Within LBN 468 are several cataloged dark Nebulae.  These objects are identified in the  annotated image.  LBN 468 is about 1,600 light years distant from Earth; the region is influenced by the massive star forming region and star cluster associated with the IRIS Nebula (NGC 7023) about 1.5 degrees of sky to the East. This image replaces an earlier image that can be seen in the archives here. Horizontal FOV is 120'.

Image center is approximately - Equatorial 2000: RA: 20h 38m 27s Dec: +6736'33"
