My impression is that Celestia has some kind of atmosphere light scattering model (or fudges it) separate from their earth shader, while Orbiter uses ONLY a shader. But I'll defer to the experts. Here is an attachment showing Celestia horizon effects. While not perfect, and still lacking...

An add-on cannot fix the physics model, and the code is closed-source. So I can only appeal to Martin to at least look at Celestia and see how Earth's horizon should look as the sun approaches and sinks below it.

Thanks. When I uncomment AtmAltLimit the reduction in ISS illumination occurs much closer to when the sun touches the horizon, as one would expect. The default is 200 km. Does anyone know what this parameter means? If it is literally the upper cutoff in the atmosphere model then it seems...

I consider this a problem unless it can be changed. For example, the ISS starts dimming into a yellowish color way before the sun starts to sink below the horizon. This simply does not happen as anyone who watches NASA TV can verify. The onset of dimming should be rapid and over with in about...
