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.
Optolong Moon & Skyglow Filter made with Schott glass, multi-coated with 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.
