Nebulae
(Hydrogen Alpha Filtered)
|
Narrow band hydrogen alpha filters greatly increase
the contrast in emission nebula. These objects
emit H-Alpha light having exactly a wavelength of
656.3 nm (Red light). I use a 6nm H-a filter,
which basically allows wavelengths of 653 to 659 to
pass. Everything else is filtered out,
including city light pollution and moonlight.
Most the data for the images on this page were taken
when the moon was very bright. Although the
images
are simple black and white, I find them pleasing in
a more artistic sense. |
