Software & Processing Notes |
-
CCDSoft, CCDStack, PixInsight
and Photoshop CS6.
-
No SDSS stars were
available for color balancing, so a standard image-train
calibration was used, as determined by
eXcalibrator v4.30, and then adjusted for altitude
extinction.
-
CCDStack for sub
exposure
calibration.
-
PixInsight
processing included sub exposure registration and integration,
the RGB combination and
the initial non-linear stretching with HistogramTransformation &
MaskedStretch.
-
PhotoShop for the
LRGB combine and final touch-up.
-
Noiseware 5, a
PhotoShop plug-in.
