NGC 6772

This ancient bubble of gas ejected by a star at the end of its life has a very distinct shape. The brighter portions almost delineate a parallelogram. This simple spiral structure could be caused by rotation of the primary star during the ejection process, or the structure could be caused by a neighboring star and its gravitational effect.

LRGB color production was used to create this image.

One iteration of L-R deconvolution (sharpening) algorithm using CCDsharp was applied to the luminance image.

Luminance = 42 minutes binned 1x1

Red = 14 minutes binned 3x3

Green = 14 minutes binned 3x3

Blue = 28 minutes binned 3x3
