DESCRIPTION:

The brightening of the night sky due to artificial lighting and atmospheric turbulence makes observing faint objects beyond the solar system challenging. However, the Explore Scientific O-III filter takes advantage of the emission lines of oxygen, filtering out all other colors and allowing for the visualization of previously invisible objects. With a narrow pass range of only 6.5 nm, this filter is essential for amateur visual astronomers and astrophotographers seeking to observe weakly glowing emission nebulae, even in difficult city conditions. Each filter is accompanied by an individual test report to ensure quality.
