Comet 17P/ Holmes: Luminance and Contour

Comet 17P/ Holmes: Luminance and Contour

Image analysis routines in AstroArt were used to enhance the original image of the comet. False colour of the luminance made the halo of the comet head more prominent. The contour filter along with false colour shows the pseudo-nucleus more clearly.
