On Jupiter, you see clearer contrasts in the cloud bands and storm regions, including the Great Red Spot. Ringlets and atmospheric details also come out better on Saturn.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dark blue greatly suppresses the red part of the spectrum. This results in a lot of contrast, but also consumes light: on smaller telescopes, the image becomes too dark quickly.<\/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-1-25-.jpg\" alt=\"Omegon Dark Blue Color Filter #38A 1.25 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 1.25 inch thread<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Compatibility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Screw into each 1.25-inch eyepiece.
