Each eyepiece in your set will then deliver 3x the magnification: a 20mm eyepiece will behave like a 6.7mm eyepiece. This way, you can instantly double the number of usable magnifications without buying new eyepieces.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The 3x magnifier is useful for planetary observers using a short-focal-length telescope, and for planetary photography using a camera instead of an eyepiece. The aluminum housing keeps the weight down.<\/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-3x-125-Barlowlens-Achromatisch.jpg\" alt=\"Bresser 3x 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>Strong factor for short telescopes and planetary photography<\/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.
