The colourful region around yellow Antares (bottom) in Scorpius and blue Rho Ophiuchi (top) in Ophiuchus. The nebulas are largely reflection nebulas, taking on the colour of the stars embedded in the nebulas. However, the field also contains a lot of emission nebulosity, hydrogen gas glowing red and magenta. Plus there are fingers of brown dark dusty nebulosity. It is one of the most colourful regions of the sky.

At right of Antares are two globular clusters, NGC 6144 (small, at 2 o'clock from Antares) and the larger Messier 4 right of Antares.

This is a stack of 5 x 8 minute exposures with the Borg 77mm astrographic apo (330mm focal length) at f/4.3 and the filter-modified Canon 5D Mark II at ISO 800. I took this March 31/April 1 from Coonabarabran, NSW, Australia.
