So to get down to the point the Intensifier was traditionally used on fall foliage because the filter increased color depth of reds. With this benefit in mind, I've actually applyied it to my landscape photography and have been experimenting with the Intensifier during the sunrise and sunset.

The Intensifier has recently became a point of interest because not only do it increase saturation in reds, it also suppress a color band that sodium vapor lights give off. These are commonly found in our simple city lights, and as any night photographer knows street lights are the most common form of light pollution.
Because of this when applied to your lens a noticeable amount of light pollution is cut out in your astro-photos. This also helps out BIG TIME in post production!
