Calibration stacking did not use dark frames, instead relying on the
built in dark suppression in the 60Da. A masked arcsinh stretch was
used then the feature mask was used to split the stars from the rest of
the image. Several iterations of masked micro curves were then applied
to brighten the nebula. The saturation was boosted in the red using a
mask and the detail was improved using multiscale decomposition. The
stars were recombined and the image cropped and scaled for the web.
