The Svbony SV260 multi-bandpass filter is a 5-bandpass broadband pass light pollution filter. Equipped with OD3 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. OD3 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 emission 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.
