With a wide 70\u00b0 field of view, this eyepiece provides a spacious and comfortable image, perfect for viewing open star clusters, nebulae and the moon in context.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The optical construction consists of five carefully placed lens elements in three groups. Thanks to full multicoating and blackened lens edges, the eyepiece offers high contrast with minimal reflections. The rubber exterior provides grip, while the infinitely adjustable eyecup also allows spectacle wearers to utilize the entire field of view.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">All eyepieces in the SWA series are parfocal: you hardly need to refocus when changing, which is pleasant during an observing session.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Key features<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>20mm eyepiece with 70\u00b0 wide angle view<\/li>\n\n\n\n<li>Ideal for wide deep-sky observations and lunar surface<\/li>\n\n\n\n<li>Five lenses in three groups for sharp and calm images<\/li>\n\n\n\n<li>Multicoating and internal baffling for high contrast<\/li>\n\n\n\n<li>Parfocal within the SWA series<\/li>\n\n\n\n<li>Infinitely adjustable eyecup, suitable for eyeglass wearers<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Specifications<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Focal length: 20 mm<\/li>\n\n\n\n<li>Barrel: 1.25\u2033<\/li>\n\n\n\n<li>Apparent field of view: 70\u00b0<\/li>\n\n\n\n<li>Optical design: 5 elements in 3 groups<\/li>\n\n\n\n<li>Full multi-coating<\/li>\n\n\n\n<li>Filter thread: yes<\/li>\n\n\n\n<li>Parfocal: yes<\/li>\n\n\n\n<li>Adjustable eye cup: yes<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Application<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The 20mm eyepiece is ideally suited for telescopes with short and medium focal lengths.
