NGC 6164 - NGC 6188 - HOO May 2022 Constellation: Norma (6164) and Ara (6188) Equipe: - Canon 6D (Original) - Telescope Hokken 200 F5 Images Ha 118x 600s - ISO 6400 O3 88x 360s - ISO 6400 Total exposure 28hs 28min NGC 6164 is a bipolar emission nebula of about 4 light-years across that lies some 4,200 light-years away in the southern constellation of Norma. It is approaching us at approximately 53.9 kilometers per second. Its symmetric gaseous shroud and faint halo surround the blue, young, central star HD 148937, the brightest member of a triple star system orbiting around each other, which fierce stellar winds – of about 8 million kilometers per hour – created this nebula. This hot, luminous O-type star is some 40 times as massive as the Sun and just 3 to 4 million years old. In another 3 to 4 million years the massive star will end its life in a supernova explosion.
