Description
Effectively cuts off the shine of the mercury and sodium lights that have been said to be a major cause of light damage in urban areas.
By allowing the light lines of OIII and Hα emitted from deep sky objects such as nebula, this filter enhances contrast during astronomical photography, and raises the nebula and galaxy from the background.
High precision polished glass base is deposited by a major Japanese vapor deposition manufacturer, and a multi-layer film is evaporated. The membrane is high density, consistency and stability.
The characteristics of this product are dependent on the angle of the light entering the light. We recommend using with a telephoto lens or telescope for proper performance. When used with a wide angle lens, the screen will produce unevenness in brightness and color balance. Please use the commercially available image processing software to adjust the color balance. We offer an in-mount frame type specifically designed for the D series popular with astrophotography enthusiast. It is very economical, without having to prepare multiple diameter filters to fit your lens or telescope.
