North is up in this image. Central in this image is the emission nebula IC 1284 also known as Sharpless 37. Just below IC 1284 are two blue reflection Nebulae vdB 118 (upper) and vdB 119 (lower). These nebulae also go by several other catalog designations and can be seen in the annotation. There Are dark nebulae in this region as well. The most significant is LDN 315. This is a dark lane structure that goes top to bottom across the image. It extends about 6 degrees of sky and this image only shows about 1 degree of that extent. These objects and some of the brighter stars are identified in the the annotated image. vdB 119 is about 40 light years distant; vdB 118 is about 185 light years distant; IC 1284 is about 1,400 light years distant. Horizontal FOV is 88'

Image center is approximately - Equatorial 2000: RA: 18h 17m 39s Dec: -19°40'19"
