The kit consists of three narrow-band filters - H-alpha, OIII and SII - with a bandwidth of 7 nm. This slightly wider pass provides a good balance between contrast, light output and exposure time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The filters allow the main emission lines of nebulae to pass through while blocking disturbing background light and light pollution. These properties make the set suitable for use in both dark sky areas and light-polluted environments. The SHO combination allows for colorful and detailed astrophotos in the Hubble palette, with rich textures and artistic interpretations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">All filters feature high-quality multilayer anti-reflection coatings, minimizing halos around stars. The optically polished glass ensures sharpness and contrast even at telescopes with fast aperture ratios up to f\/3. The robust 2\u2033 filter cells fit standard filter wheels and adapters.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Observation goals<\/strong><br>This filter set is ideal for astrophotographers who want to photograph emission nebulae such as the Rosette Nebula, the Veil Nebula or the Crab Nebula with creative color combinations. The 7 nm bandwidth makes the filters particularly suitable for beginners and advanced photographers who want to combine relatively short exposure times with sufficient contrast and detail.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Specifications<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Type: Narrowband filter set (H-alpha, OIII,
