The set contains five filters: a UV\/IR blocking filter, three color filters (red, green and blue) and an infrared filter (IR685). Together they form a complete basis for capturing planets in both visible and near-infrared light.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The UV\/IR blocking filter provides a natural and sharp image in the visible spectrum. The red, green and blue filters allow you to photograph individual channels that are later combined to create a realistic color image. The IR685 filter allows only infrared light to pass through. That filter is particularly valuable because it reduces the disturbing influence of turbulent air layers, making details more visible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This filter set is tailored to the characteristics of different planets:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Mercury, Venus, Uranus and Neptune<\/strong>: IR685 infrared filter for stable and high-contrast images.<\/li>\n\n\n\n<li><strong>Jupiter and Saturn<\/strong>: UV\/IR blocking filter and the three color filters for rich colors and clear details, such as cloud bands and the Cassini separation.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Thanks to the high-quality multiple coating, light transmission remains high and reflections are minimized. The sturdy aluminum mount ensures durability and a secure fit in any 1.25\u2033 camera system or eyepiece mount.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Observation goals<\/strong><br>The Optolong Planetary Filter Set 1.25\u2033 is ideal for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Photography of planets with monochrome cameras<\/li>\n\n\n\n<li>Building color images through red,
