The Optolong Moon & Skyglow Filter is perfect for both visual and photographic applications. You'll notice a darker background sky due to the blocking of natural skyglow at 589nm as well as emissions from lights that cause artificial light pollution. With a darker background the contrast will increase between the sky and the object, revealing more details. Great for nebulae, galaxies, globular star clusters, planetary nebulae and even the moon.
The Optolong Moon & Skyglow Filter is made with Schott glass that has been multi-coated with an ion-assisted deposition technology to ensure scratch resistance and stability on the central wavelength, or CWL. Each filter cell is made of lightweight, strong metal and is CNC machined, sand-blasted, black anodized, and then laser engraved.
