Calibration, stacking, background noise reduction
and
initial star size reduction done with Images Plus .
Background correction and further noise
reduction applied in Paint
Shop Pro . The noise reduction resulted
in some low spatial frequency blobs that were fixed
using the technique detailed here
. LMS
processing was used to preserve the core while stretching the fainter
areas. The star colour was enhanced and slight
tracking error was removed . Finally the image
was sharpened using Focus
Magic and resized for the web. |
