Every eyepiece in your set will therefore provide 2x the magnification: a 20 mm eyepiece behaves like a 10 mm eyepiece. This instantly doubles the number of usable magnifications without buying new eyepieces.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The 2x is the most commonly used factor and the safest choice for a first Barlow: it doubles your range without the image quickly becoming too dark or too unsettled. The multi-coated lenses keep the image bright and high-contrast.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/11\/Bresser-2x-125-Barlow-Lens.jpg\" alt=\"Bresser 2x Barlow lens 1.25 inch\" title=\"\"><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Features<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Achromatic lens design minimizes chromatic aberrations<\/li><li>Doubles the range of your existing eyepiece set<\/li><li>Metal housing with a set screw<\/li><li>Works with any 1.25-inch eyepiece, including with filter threads in the eyepiece.<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Compatibility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Fits any 1.25-inch (31.7 mm) focuser or zenith mirror. Stick to your telescope\u2019s realistic maximum magnification: approximately twice the aperture in millimeters. So use the Barlow lens with your medium-length eyepieces, not your shortest ones.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Specifications<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Magnification factor<\/strong><\/td><td>2x<\/td><\/tr><tr><td><strong>Optical design<\/strong><\/td><td>Achromatic<\/td><\/tr><tr><td><strong>Coating<\/strong><\/td><td>Multi-coated<\/td><\/tr><tr><td><strong>Mount<\/strong><\/td><td>1.25 inches (31.7 mm)<\/td><\/tr><tr><td><strong>Housing<\/strong><\/td><td>Metal, with set screw<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">You can find more accessories for this brand at the <a href=\"\/en\/brands\/bresser\/\">Bresser 1TP5 Page<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>Bresser 2x Barlow lens with achromatic, multi-coated lens design.
