The red tint increases contrast and emphasizes features that often go unnoticed without the filter, such as polar caps and dust storms.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With Jupiter and Saturn, the filter also helps to distinguish structures in the atmosphere. Red light attenuates less strongly than the deeper #25 red wavelengths, and therefore remains more widely usable.<\/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-23A-lichtrood-2-.jpg\" alt=\"Omegon Light Red Color Filter #23A 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>Wratten #23A, light red<\/li><li>Strong contrast on Mars<\/li><li>Less light loss than red #25<\/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.
