The Optolong H-alpha 7 nm 2" filter is a high-performance narrowband line filter designed for astrophotography and visual observation of deep-sky objects. It isolates the hydrogen-alpha emission line at 656 nm, significantly enhancing contrast and revealing fine nebular structures, even under strong light pollution. By blocking unwanted artificial and natural skyglow wavelengths, it delivers sharper images with improved detail and background darkness. This filter is particularly well suited for capturing emission nebulae.
