The set consists of three high-quality narrowband filters - H-alpha, OIII and SII - with a bandwidth of only 3 nm. These extremely narrow pass areas ensure that only the relevant emission lines are captured, while light pollution and interfering background light are almost completely suppressed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This precision allows you to photograph emission nebulae with exceptional contrast and detail. The SHO combination (H-alpha, OIII, SII) makes it possible to produce astrophotos in the famous Hubble palette, showing structures and colors in a scientifically inspired way.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The filters feature multiple anti-reflection coatings, which ensure high transmission and minimal halos around bright stars. The optically polished glass ensures sharp images even on telescopes with fast aperture ratios (up to f\/3). Thanks to the 36 mm unframed design, they fit seamlessly into most standard filter wheels for astrophotography.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Application<\/strong><br>This filter set is ideal for deep-sky astrophotography from light-polluted areas. They come into their own when shooting emission nebulae such as the Rosette Nebula, the Veil Nebula or the North American Nebula. By combining H-alpha, OIII and SII filters, you can compose images in the iconic SHO or Hubble palette, beloved of astrophotographers worldwide.<\/p>\n\n\n\n<p
