I don't know if this will help, this is an adaptation from a tutorial I
was following. I vaguely remember some improvement in making the
absorption media and scattering media in separate declarations. The
tutorial advised dividing the color statement by the scale used to match
the radius of the atmosphere.
---code
#declare atmos = media { file://atmospheric scatter
scattering {4, rgb <.6,.5,1>/8280.5}
intervals 1 file://set to 10 for final
samples 2, 20
confidence 0.9999
variance 1/1000
density {
spherical
color_map{
[0, rgbf <0,0,0,1>]
[.075, rgbf <.75, .75, .75, 1>]
[.15 rgbf 1]
[.6, rgbf 1]
[.61, rgbf <0,0,0,1>]
[1, rgbf <0,0,0,1>]
}
}
scale 8280.5}
#declare atmos2 = media { file://atmospheric absorption
absorption rgb <.6, .5, 0>/8280.5
intervals 1 file://set to 20 for final
samples 2, 20
confidence 0.9999
variance 1/1000

}
}
