| Notes | This image of the Western Veil or Witches Broom
and Pickering's Triangle in Cygnus is a combination of 17 hours of
narrowband data.
I attempted to fit both NGC 6960 and Pickering's Triangle in the frame and
could have used a bit more chip. Initial processing was performed in CCDStack including Positive Constraint Deconvolution for each narrowband channel (150 iterations). Final processing was performed in PS CS2 including Unsharp Mask and desaturating the star field (red and maroon) to reduce the reddish halos around the stars. |
