The 305 mm mirror collects almost 2,000 times more light than the naked eye. Faint nebulae and distant galaxies that remain vague in smaller scopes show structure and detail here. For the visual observer, this is the point where deep-sky truly comes to life.<\/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=\"32239\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/11\/Bresser-N-305-1525-Telescoop-Dobson-Messier-Hexafoc-DOB-1.jpg\" alt=\"Bresser N 305\/1525 Dobson telescope on rocker box\" class=\"wp-image-32239\" 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\/11\/Bresser-N-305-1525-Telescoop-Dobson-Messier-Hexafoc-DOB-6.jpg\" alt=\"The 2.5-inch Hexafoc focuser of the Bresser N 305\/1525\" class=\"wp-image-32240\" 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\">12-inch parabolic optics<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The parabolic primary mirror delivers sharp, high-contrast images.

The rockerbox has metal connectors and is dismantable.
