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.
