Two-meter focal length and ten-inch aperture: the image scale and light for galaxies and planetary nebulae at observatory level.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A Ritchey-Chr\u00e9tien uses two hyperbolic mirrors: the design of virtually every professional observatory. The result is a large, coma-free field of view without a corrector: stars remain round all the way to the edges of the sensor.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Carbon-Volledige-buis-Ritchey-Chretien-Pro-RC-250-2000-OTA-4.jpg\" alt=\"Omegon Pro RC 250\/2000 carbon Ritchey-Chr\u00e9tien\" title=\"\"><\/figure>\n<\/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:50%\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Carbon-Volledige-buis-Ritchey-Chretien-Pro-RC-250-2000-OTA-3.jpg\" alt=\"The 3-inch rotatable focus of the Omegon RC 250\" 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:50%\">\n<h4 class=\"wp-block-heading\">3 inch focus lens: wide field of view, precise framing<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The 3-inch focus ring also illuminates large sensors without vignetting and rotates for the correct image cut without having to disassemble the camera train. The tilt adapter aligns the sensor exactly at right angles, and the quartz mirrors keep the focal point stable in the face of temperature fluctuations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The internal baffles keep the contrast high; the Losmandy eagle-tail sounds like a heavy piece of equipment in the EQ8 class.<\/p>\n<\/div>\n<\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Included<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Ritchey-Chr\u00e9tien optics 250\/2000 with hyperbolic quartz mirrors<\/li>\n\n\n<li>Carbon tube<\/li>\n\n\n<li>3 inch rotatable focus ring<\/li>\n\n\n<li>Tilt adapter<\/li>\n\n\n<li>Integrated baffles<\/li>\n\n\n<li>Losmandy dovetail<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Featured accessories<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The Omegon Pro UHC 2-inch filter (89 euros) removes emissions of particulate matter, and the Omegon Powerbank 10k 12V (39.90 euros) powers the setup on site.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">For whom yes, for whom no<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Well: demanding astrophotographers and small starwatchers who want maximum image scale in a closed tube. Not: those who want 12 inches and larger; that's where the truss line begins, with better ventilation and less weight per centimeter of opening.
