Omegon Brightsky ED-APO Binoculars 30\u00d7100 \u2013 90\u00b0: ED-APO giant binoculars with interchangeable eyepieces<\/strong><\/h2>\n\n\n\n

The Omegon Brightsky ED-APO 30\u00d7100 with 90-degree viewing angle is a giant binoculars with interchangeable 1.25-inch eyepieces, magnesium housing and nitrogen filling. You can buy the bare binocular here with two 18 mm eyepieces; the case and mounting kit are sold separately.<\/p>\n\n\n\n

With a 100 mm aperture, you view with both eyes objects that are already impressive in a single 100 mm refractor. This is the culmination of the Brightsky line and requires a serious mount.<\/p>\n\n\n\n

100 mm at 30x: the maximum with both eyes<\/h4>\n\n\n\n

Two 100 mm objectives effectively turn this binoculars into a double refractor. Globular clusters like M13 resolve into stars at the edge, in M42 you see the Trapezium stars separated from each other, and the M81 Galaxy shows a clear core.<\/p>\n\n\n\n

At 30x magnification, the field of view is 2.1 degrees, still four full moons wide. The 3.3 mm exit pupil suits a dark-adapted eye well and keeps the sky background dark.<\/p>\n<\/div>\n<\/div>\n\n\n\n

90-degree viewing angle for the zenith<\/h4>\n\n\n\n

With a 90-degree viewing angle, you look into the eyepieces from above, just like with a refractor with a star diagonal. Objects directly overhead, where the sky is darkest and most transparent, can be viewed without straining your neck. That is why most astronomical users choose this variant.<\/p>\n\n\n\n

For observations low on the horizon, the 90-degree position is less convenient: you then stand bent forward. For predominantly daytime observation, the 45-degree version makes more sense.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Apochromatic lenses without color cast<\/h4>\n\n\n\n

The ED-APO version uses objective lenses with ED glass. Color errors that appear in a standard achromat as purple fringes around bright stars, the lunar limb, and high-contrast daytime objects are virtually absent here. Stars are small white points right up to the edge of the field.<\/p>\n\n\n\n

The difference compared to the standard Brightsky is most clearly visible with the moon, Jupiter and Saturn, and during the day with branches against a clear sky. For faint nebulae, the gain is smaller: there, aperture is what matters most.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Interchangeable eyepieces and filter thread<\/h4>\n\n\n\n

By default, two 18 mm flatfield eyepieces with a 65-degree apparent field of view are included. They are 1.25 inches, so you can replace them with any pair of eyepieces from your telescope case. For example, two 10 mm eyepieces provide a higher magnification for the moon and planets.<\/p>\n\n\n\n

Both eyepiece holders have 1.25-inch filter threads. A pair of UHC filters enhances the contrast of nebulae from a light-polluted environment. Each tube has its own focusing mechanism, allowing you to precisely adjust the viewer to your eyes.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Mounting a tripod<\/h4>\n\n\n\n

Almost 7 kg of optics on a long tube: here the Neptune fork mount is not an accessory, but a requirement. In combination with a pier tripod or the carbon tripod, you can look up comfortably from a chair without the image shaking.<\/p>\n\n\n\n

This binoculars cannot be used on a standard photo tripod. Anyone who wants the complete package all at once should choose the set with the Neptune fork mount and tripod.<\/p>\n<\/div>\n<\/div>\n\n\n\n
