Omegon Redline SW 5 mm Eyepiece 70\u00b0 (1.25 and 2 inch): 70-degree field of view with ED optics<\/strong><\/h2>\n\n\n\n

The Omegon Redline SW 5 mm combines a 70-degree field of view with an ED lens element and a generous 20 mm eye relief. High magnification that is usable on medium-sized telescopes on almost any clear night.<\/p>\n\n\n\n

The holder is double-designed: the eyepiece fits directly into both a 1.25-inch and a 2-inch focuser, without an adapter.<\/p>\n\n\n\n

ED optics for color purity<\/h4>\n\n\n\n

The ED element keeps color errors low, and the multi-layer coating on all air-to-glass transitions maximizes light transmission. The result is a sharp, high-contrast image all the way to the edge, even on faster telescopes.<\/p>\n\n\n\n

20 mm eye relief and 70 degrees<\/h4>\n\n\n\n

This combination is what the Redline is known for: the wide field of view of a wide-angle eyepiece combined with the relaxed viewing experience that eyeglass wearers need. On a Dobsonian telescope without a tracking motor, objects stay in view significantly longer.<\/p>\n\n\n\n

Ready for photography<\/h4>\n\n\n\n

Under the eyepiece is an M43 thread. You can use this with an adapter to connect an eyepiece projection camera, for example, for moon photography with a system camera.<\/p>\n\n\n\n

What can you see with a 5 mm lens?<\/h4>\n\n\n\n

On a 150\/750 Newtonian, 5 mm gives a magnification of 150x, on an 8-inch Dobson with 1200 mm 240x. Jupiter and Saturn show their detail with 70 degrees of space around them.<\/p>\n\n\n\n

Even compact planetary nebulae gain visibility at this magnification.<\/p>\n\n\n\n

Featured accessories<\/h3>\n\n\n\n

The Redline series ranges from 3.5 to 32mm with the same eye relief and eye distance: a set of two or three focal lengths covers everything from planetary detail to overview. An Omegon moon filter dims the bright moon image at longer focal lengths.<\/p>\n\n\n\n
