Software & Processing Notes |
-
CCDSoft, CCDStack,
Photoshop CS6, PixInsight and Noel Carboni's actions.
-
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 to calibrate the sub exposures.
-
PixInsight for
registration and stacking the sub exposures, RGB creation,
gradient removal, the initial non-linear stretching and star
dimming with MorphologicalTransformation
-
PhotoShop for the
LRGB combine, adding Ha data to the red channel & final touch-up.
-
Noiseware 5, a
PhotoShop plug-in.

Comment |
The nebula is shown
with North to the top.
IC 405 (also known as
the Flaming Star Nebula, SH 2-229, or Caldwell 31) is an
emission/reflection nebula in the constellation Auriga, about 1,500
light-years from Earth. The rippling dust and gas lanes surround the
star AE Aurigae and give the impression that the star is aflame...
hence the nebula's popular name.
The star, AE Aurigae, creates the red glow by energizing the
nebula's hydrogen. The blush areas are created by dust that scatters
and reflects the stars blue light. |
