Kase Neutral Night Clip-In Filter for Select Sony Alpha Full frame Cameras

Designed to improve image quality during astrophotography sessions in urban areas, this Light Pollution Clip-In Filter for Select Sony Alpha Cameras from Kase 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 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.

Made of B270 optical glass, this filter is engineered for longevity with improved hardness to make it shock and scratch resistant, and with Nano multi-coatings that allow water and oil to bead and be cleaned off without leaving residue. This clip-in filter mounts inside the camera body, in front of the image sensor, adding the benefit of sensor protection to its main application. The included matte black shading fabric reduces the potential for stray lens flare. Installation is quick and easy, and removing it is simple using the included plastic removal tool.Compatible Sony Alpha Cameras
