Equipped with OD4 cut-off depth and over 90% peak transmittance, the filter is designed to isolate 6-level light pollution and make light wave transmission maximum to enhance deep-sky details and improve the visibility of deep-sky objects. OD4 cut-off depth filters out the unnecessary light produced by artificial lighting including mercury vapor lamps, both high & low-pressure sodium vapor lights, and the unwanted natural light caused by neutral oxygen in our atmosphere (i.e. skyglow). More than 90% peak transmittance reduces the light loss and delivers images of broadband-emitting objects, such as galaxies, reflection nebulae, and globular clusters, with minimal color cast. The SV260 filter effectively brings you a better shooting experience when starfield shooting and deep-sky photography.
