This is a reprocess of this glorious image of space. About 11 hours of data at various exposure times and ISO settings. All up about 105 light frames. All at 100mm taken on the Canon 600D
Antares, also known by its Bayer designation Alpha Scorpii (abbreviated to α Scorpii or α Sco), is the seventeenth brightest star in the nighttime sky and the brightest star in the constellation Scorpius, and is often referred to as “the heart of the scorpion”. Along with Aldebaran, Regulus, and Fomalhaut, Antares comprises the group known as the ‘Royal stars of Persia’. It is one of the four brightest stars near the ecliptic. Rho Ophiuchi (ρ Ophiuchi) is a multiple star system in the constellation Ophiuchus. It consists of at least two blue subgiants, ρ Oph A and ρ Oph B, both of which are of class B.
