Rho Ophiuchi molecular cloud

Almost gave up on processing this frame. The signal collected from the light-polluted coast of Montenegro was unimpressive. The August trip to the excellent skies of Stara Planina (Bortle 2 at 1600 meters altitude - it's fire) only allowed adding 40 minutes before Antares set behind the neighboring mountain. Was motivated to return to this material by the well-known Cuiv, who showed on his YouTube channel what can be extracted from an eight-minute stack of Rho Ophiuchi.
