This beautiful image, created by astrophotographer Rogelio Bernal Andreo, contains not one, but three celestial regions — as seen in a wide-field view.
The first of which, is the Rho Ophiuchus – Antares region (the colorful area in the upper right), which is home to a binary star system, with Antares (in yellow) and ρ Ophiuchi (in blue). Also contained wherein are the Blue Horsehead nebula (also known as IC 4592 — not to be confused with the Horsehead nebula in the Orion Molecular Cloud) and Sharpless 1 (or Sh 2-1). All of this area is located about 400 light-years from Earth (in the constellation of Ophiuchus).
You can also see M4, a cluster of stars that lie between Antares and the reddish-emission nebula in addition to a few more small nebulae.
