This image has captured a field of 15×10 degrees in span just north of the Pipe nebula which has been displayed in previous page.
This star field is equivalent to the Milky Way of southern Ophiuchus, one of most conspicuous dark nebulae have been floating visible from Japan.
Although it's hard to detect detailed shapes with naked eyes, easy to take pictures of various shaped mesh-like dark nebulae only with a wide-field photo lens.

This image shows you B63 positioned around the center of the first image in this page.
The nebula has a span of a bit smaller than 2 degrees in east west; maybe you can recognize that the nebula resembles a curved sausage.
B63 is one of striking one around this field, only small binocular can aid you to appreciate the unique shape.
