This flattener flattens the field without changing the brand point spacing, ensuring that the entire image is in focus.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike model-specific flatteners, this is a universal version for refractors from f\/4 to f\/8. This makes it the logical choice for anyone who owns a refractor for which no dedicated flattener exists.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-3 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\"><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-Field-Flattener-2-.jpg\" alt=\"2-inch Omegon field flattener for refractors\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-Field-Flattener-2-1.jpg\" alt=\"2-inch Omegon field flattener for refractors\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-Field-Flattener-2-2.jpg\" alt=\"2-inch Omegon field flattener for refractors\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-Field-Flattener-2-3.jpg\" alt=\"2-inch Omegon field flattener for refractors\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-Field-Flattener-2-4.jpg\" alt=\"2-inch Omegon field flattener for refractors\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-Field-Flattener-2-5.jpg\" alt=\"2-inch Omegon field flattener for refractors\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-Field-Flattener-2-6.jpg\" alt=\"2-inch Omegon field flattener for refractors\" title=\"\"><\/figure><\/figure>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8d39b2df wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:38%\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-Field-Flattener-2-1.jpg\" alt=\"2-inch Omegon field flattener for refractors\" title=\"\"><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:62%\">\n<h4 class=\"wp-block-heading\">Adjustable to your brand point distance<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The correct working distance depends on the brand point distance of your refractor and ranges from 108 to 128 mm. The included extension tubes, which allow for a chip distance of up to 53 mm, help you set up that distance precisely.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once determined, note down the combination: after that, the setup can be repeated in a single action.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8d39b2df wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:38%\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-Field-Flattener-2-2.jpg\" alt=\"2-inch Omegon field flattener for refractors\" title=\"\"><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:62%\">\n<h4 class=\"wp-block-heading\">M48 through and through<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Telescope side and camera side are both M48, the size of 2-inch filters and modern camera adapters.
