This page shows you a close-up image around the Pipe Nebula captured with a telephoto lens. You can detect only dark patch in the Milky Way through binoculars with your naked eyes, but this image can show you fairly complicated structures. The pipe nebula has many individual catalogue numbers of dark nebula. In upper center, this image includes the Snake Nebula at the leg of Ophiuchus.

The northern part of the Pipe Nebula lies within the Milky Way in the southern region of Ophiuchus, which has the most well-developed dark nebulae visible from Japan. Notable features include B268, the largest, and B63, which has a distinctive curved sausage-like shape. While it is challenging to discern clear outlines with the naked eye, wide-angle lenses can capture various dark nebulae drifting in a mesh-like pattern.
This image has cropped with an equivalent focal length of 120 mm.
