Near the star Rho Ophiuchi, in the extreme southwest corner of Ophiuchus, is a region of strangeness and beauty. The star itself is enmeshed in a vast diffuse nebulosity, IC 4604, too faint to be studied visually. But from this nebulous region a number of dark narrow lanes flow out toward the east, appearing like black tentacles obscuring the starry background. These vacant lanes end near the star Xi Ophiuchi. Near Xi also is the large and strangely shaped dark cloud B63. This is an extraordinary region, described by Barnard as making a picture almost unequalled in interest in the entire heavens.
