On Jupiter, you can see clearer cloud bands, storm regions, and details such as the Great Red Spot. On Saturn, rings and atmospheric structures become more visible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Additionally, the filter dims bright moonlight. The strong attenuation in the red part of the spectrum does, however, require a sufficient aperture.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-Filters-kleurfilter-38A-donkerblauw-2-.jpg\" alt=\"Omegon Dark Blue Color Filter #38A 2-inch\" title=\"\"><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Features<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Warts #38A, dark blue<\/li><li>Strong contrast on Jupiter and Saturn<\/li><li>Dim field moonlight<\/li><li>Standard 2-inch thread<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Compatibility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For telescopes with a 2-inch light path and a generous aperture.
