On Jupiter and Saturn, it enhances the contrast of cloud bands and storm regions. On Mars, it helps distinguish polar caps and nebulous structures.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Blue #80A is less intense than the dark blue #38A and keeps the image brighter. Those who want to start with a single color filter usually choose this one.<\/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-80A-blauw-1-25-.jpg\" alt=\"Omegon Blue Color Filter #80A 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 #80A, blue<\/li><li>Widely deployable on Jupiter, Saturn, and Mars<\/li><li>Does the image appear brighter than #38A?<\/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\">Screws into each 1.25 inch eyepiece. Also useful for the moon. Color filters work best on telescopes with apertures of approximately 100 mm or larger: the filter costs light, and the aperture needs to be able to capture it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Specifications<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Type<\/strong><\/td><td>Color filter<\/td><\/tr><tr><td><strong>Wart number<\/strong><\/td><td>#80A<\/td><\/tr><tr><td><strong>Color<\/strong><\/td><td>Blue<\/td><\/tr><tr><td><strong>Mount<\/strong><\/td><td>1.25 inches<\/td><\/tr><tr><td><strong>Glass<\/strong><\/td><td>Tinted optical glass<\/td><\/tr><tr><td><strong>Observation goals<\/strong><\/td><td>Moon and planets<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">You can find more accessories for this brand at the <a href=\"\/en\/brands\/omegon\/\">Omegon brand page<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>Blue Wratten #80A color filter, the most versatile color filter for planetary observation.
