| Processing |
This one is
heavily processed, while the galaxy is quite easy to bring out the star
streams require a lot of work. Split star processing with masked
stretches was used to bring out the streams. The initial mask was made
from the sum of the red, green and blue channels. The feature mask tool
was used to remove most of the stars from the mask. Several iterations
of blurring and stretching were used to make the streams
visible in the mask. Finally the mask was used on all stretches of the
data and was noise reduced using the frequency filter tool applied with
an inverse luminance mask to protect the brighter areas of the image.
