Kase KW-150-NT Overview
Designed to improve image quality during astrophotography sessions in urban areas, the Kase 150x150mm Wolverine Neutral Night Light Pollution Filter reduces the appearance of light pollution from artificial light sources such as commercial or residential buildings, brightly lit billboards, streetlamps, and sports and entertainment venues that can produce a yellowish cast in your images.

These artificial light sources create a form of light pollution known as sky glow, where individual stars, the Milky Way, and other astronomical objects in the night sky are obscured. Employing this filter can improve the image quality by blocking the yellow light from sodium-vapor lamps, mercury-vapor lamps, or low Color Rendering Index LEDs. By preventing the dominant wavelengths of light associated with the color of those lamps from being recorded, the visibility of astronomical objects is enhanced. An additional IR-blocking lens coating is applied that prevents ghosting and blurriness from appearing on your images when using sensors that are sensitive to those low wavelengths.

This version of the Light Pollution Filter is offered unmounted for custom applications and can fit into standard 150x150mm filter frames. Made of B270 optical glass, the filter is engineered for longevity with improved hardness to make it shock and scratch resistant, with multi-coatings that allow water and oil to bead and be cleaned off without leaving residue.
