20150314 NGC6302 Butterfly Nebula LRGB
NGC 6302 - the Bug Nebula or Butterfly Nebula, is a bipolar planetary nebula in the constellation Scorpius. The structure in the nebula is among the most complex ever observed in planetary nebulae and its central star is one of the hottest in the galaxy, with a surface temperature > 200,000 K, implying that the star from which it formed must have been very large. Its small angular size (about 80 x 45 arc secs) is evidenced by the fact that this image was taken with a Planewave 20" (0.51m) CDK Astrograph, fl 2280mm (0.66 Focal Reducer Fitted) f/4.5
