Software & Processing Notes

  • CCDSoft, PixInsight & Photoshop CS6.

  • eXcalibrator v6.1 for (g:r)(b:r) color balancing.

  • PixInsight processing includes calibration,  registration and stacking the Ha & RGB data, creating the mosaic, gradient repair, non-linear stretching with HistogramTransformation, LocalHistogramEqualization.

  • PhotoShop to add the Ha data & final touch-up.


North is to the top.

The emission nebula on the left is famous partly because it resembles Earth's continent of North America. To the right of the North America Nebula, cataloged as NGC 7000, is a less luminous nebula that resembles a pelican dubbed the Pelican Nebula, cataloged as IC 5070. The two emission nebula measure about 50 light-years across, are located about 1500 light-years away, and are separated by a dark absorption cloud. The nebulae can be seen with binoculars from a dark location. Look for a small nebular patch north-east of bright star Deneb in the constellation of Cygnus.
