North America and the Pelican in Hydrogen-Alpha Light
One of my favorite photography targets gets a special look! My previous color image of this object, shown here, was taken only with red, green, and blue filters. This image is taken with a special, narrowband filter that highlights the particular hydrogen gases that emit from this nebulous region. This allows for much more detail in the wisps of the nebula itself, much more than with traditional RGB filters. While my previous RGB image is quite pleasing, even award winning ("Best Deep Sky Photograph" at the 2004 Texas Star Party), it lacks some of the detail that is possible.
Two areas of the nebula, shown highlighted below, are especially well known and best demonstrate the detail possible when shooting in Hydrogen-alpha light.
The first of these regions is the "Gulf Coast" area of NGC7000 itself:
And second, there is the following shot of the "neck" area of the Pelican, IC 5070:
