NGC6188 and NGC6164/6165 in the Hubble Palette. Taken from Brisbane, Australia under Bortle 6 skies. Shot with a William Optic ZenithStar 61 scope on an HEQ5 Pro mount and a ZWO ASI1600MM Pro camera. Using 7nm Sulphur, Hydrogen and Oxygen emission filters. Link to zoomable image https://astrob.in/o0rern/0/
Shot over 3 consecutive nights between the 18th and 20th of April for a total of 12 1/2 hours of imaging time.
NGC 6188 is an emission nebula located about 4,000 light years away in the constellation Ara. The bright open cluster NGC 6193, visible to the naked eye, is responsible for a region of reflection nebulosity within NGC 6188.
NGC 6188 is a star forming nebula, and is sculpted by the massive, young stars that have recently formed there – some are only a few million years old. This spark of formation was probably caused when the last batch of stars went supernova.
NGC6164 and 6165 are the bright bubble in the lower right section of the image. This nebula is the result of the mass ejection by an infrequent star type, O6.5f. Only 5 such stars are known, three in our galaxy and two in the Small Magellanic Cloud. This nebulosity is the result of a two-step fierce mass ejection from the central star.
