Omegon Horizon AC 90\/650 3.5\" Achromatic Refractor: More Aperture in a Modern Package<\/h2>\n\n\n\n

The Omegon Horizon AC 90\/650<\/strong> is the largest model in the Horizon line: 90mm aperture and 650mm focal length (f\/7.2). More light and a wider field of view than the 70mm models, with the same complete equipment including smartphone adapter and Bluetooth remote release.<\/p>\n\n\n\n

The Horizon accessory package is more complete than usual in this class: LED finder, 25 mm and 10 mm Pl\u00f6ssl eyepieces, 2x Barlow lens, 90-degree Amici prism for an upright and laterally correct image, extension tube, smartphone adapter, and a Bluetooth shutter release for vibration-free photos.<\/p>\n\n\n\n

90 mm and a Crayford on ball bearings<\/h4>\n\n\n\n

The 90 mm lens captures approximately 165 times more light than the naked eye: the entire Moon in one go, bright nebulae and star clusters, and sharp planetary detail. The Crayford focuser runs on ball bearings, without play, allowing for smooth focusing even at higher magnifications.<\/p>\n\n\n\n

With the Pl\u00f6ssl eyepieces, you view at 26x and 65x; with the 2x Barlow, up to 130x. That's also about the limit of the useful range for this f\/7.2 achromat: beyond that, color fringing becomes visible.<\/p>\n<\/div>\n<\/div>\n\n\n\n
