Filter for astronomical observation and shooting that cut light pollution.When observing and shooting nebula, stars, comets, etc., it is an optical cut filter that removes unnecess ary light (light pollution) such as the city lights and transmits the light of the astronomical objects.It is a filter that cuts artificial light, such as mercury lights and sodium lights that cause light pollution, and the light from most astronomical bodies is transmitted.Removes light pollution that hinders astronomical observations and shooting, and realizes clear statues.In addition, since only light pollution is selected and removed, the color balance changes are as low as possible, making it easier to process image processing at the time of shooting.The IAD (Ion Assisted Deposition) system coats the multilayer film, improving durability and hardness than the normal coat.Furthermore, since synthetic quartz glass is used, the surface accuracy of the filter is extremely high and can be shot with high image quality.The spectroscopic characteristics shift to the short -wavy characteristics to the diagonal shooting rays, so it is recommended that you use a narrow angle of telephoto lens.- asbestos non -containing ROHS Directive Response J-Moss not eligible Environmental Self -assertion mark Other environments and safety standards Radio Law Reference Telecommunications Business Law Electrical Equipment Safety Law Remarks Radio Law non -target Telecommunications Business Law non -target Electrical Appliance Safety Law non -target Legal Related Confirmation Date 20140304 Show more
