It combines some very interesting regions:
• the Blue Horsehead Nebula, with its soft blue reflection dust glowing around Nu Scorpii
• the Rho Ophiuchi Cloud Complex, one of the most colorful areas of the entire Milky Way
• and on the left, the beautiful red Hα emission regions (Sh2-7 and Sh2-1), adding a striking contrast of ionized hydrogen against the cooler dust clouds
