Massive clouds of ionized hydrogen and oxygen glow brightly among dark lanes of cosmic dust in the Rosette Nebula. Spanning 65 light years across and located 5200 light years away in the constellation of Monoceros, the Unicorn, this deep space object is one of the most stunning of the night sky.
Over five hours of exposures were combined for this image, shot with my rooftop telescope using narrowband filters which allow very specific wavelenghts of light emmited by the nebula to pass, blocking light pollution and enabling this kind of deep space photography from the highly polluted urban skies of Buenos Aires.
