NGC 6979 Pickering's Triangle

Recommended Posts

Mornin',

finished another picture. It shows a section of Pickering's triangle. This celestial object was discovered in 1904 by Williamina Fleming. It was commissioned by Edward Charles Pickering, director of the Harvard College Observatory, to examine photographic plates and catalog the stars and other celestial bodies. As was usual at the time, newly discovered objects were named after the employer and not after the assistant of the observatory who made the discovery. Williamina Fleming made many discoveries during her work for Edward Pickering. One of the most famous objects she discovered is the Horsehead Nebula.

The picture was worked out as HaOIIIRGB. Besides the narrowband data, which clearly show the structures, there are also many hours of RGB in the image, which give the whole thing the beautiful colours.
