The fast f\/3.9 optics collect a lot of signal in a short exposure time: precisely what you want for nebulae and galaxies. Visually, the same optics provide strikingly wide fields at low magnification.<\/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-full\"><img decoding=\"async\" data-id=\"31836\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/10\/Bresser-N-203-800-Telescoop-Messier-NT-203S-Hexafoc-EXOS-2-1.jpg\" alt=\"Bresser N 203\/800 on EXOS-2 mount fully assembled with viewfinder, counterweight and telescope tube.\" class=\"wp-image-31836\" 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\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/10\/Bresser-N-203-800-Telescoop-Messier-NT-203S-Hexafoc-EXOS-2-2.jpg\" alt=\"Bresser N 203\/800 telescope mount on robust tripod with double counterweights and carrying handle.\" class=\"wp-image-31837\" title=\"\"><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h4 class=\"wp-block-heading\">Fast 8-inch optics<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The 203-mm parabolic mirror captures more than 800 times as much light as the naked eye. With an 800-mm brand focal length (f\/3.9), this is one of the fastest Newtonian telescopes in its class. The classic aluminum tube is factory-prepared for a 10:1 fine-focus reduction and a coma corrector, which is highly recommended for photography at this aperture ratio. With the 26 mm eyepiece, you\u2019ll have a magnification of 31x.<\/p>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">The EXOS-2 mount<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The EXOS-2 is a German equatorial mount of the EQ-5 class with a payload capacity of up to 13 kg. With the polar finder scope, you align quickly, and with the slow-motion cables, you track objects smoothly. If you want automatic tracking later, the mount can be upgraded with a motor set or the complete StarTracker GoTo system. For long exposures, the GoTo version with an ST-4 port is the more complete foundation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Included<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Newtonian optics 203\/800 with parabolic primary mirror<\/li>\n\n\n\n<li>2.5-inch Hexafoc focuser with eyepiece adapter<\/li>\n\n\n\n<li>EXOS-2 equatorial mount with tripod<\/li>\n\n\n\n<li>26 mm Super Pl\u00f6ssl eyepiece (1.25 inch)<\/li>\n\n\n\n<li>8\u00d750 viewfinder<\/li>\n\n\n\n<li>Setting circles, polar scope and slow-motion cables<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Featured accessories<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A comma corrector from our <a href=\"https:\/\/www.telescoop.nl\/en\/telescope-accessories\/astro-photography\/other-astrophotography-accessories\/optical-accessories\/\">Optical accessories<\/a> at f\/3.9 is the most important photo upgrade.
