Omegon Brightsky 90° Binoculars 30×100

Omegon Brightsky 90° Verrekijkers 30×100: reuzenverrekijker met wisseloculairs

De Omegon Brightsky 30×100 met 90 graden inkijk is een reuzenverrekijker met verwisselbare 1,25 inch oculairs, magnesium behuizing en stikstofvulling. Je koopt hier de kale kijker met twee 18 mm oculairs; koffer en montering kies je apart.

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.

100 mm at 30x: the maximum with both eyes

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.

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.

90-degree viewing angle for the zenith

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.

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.

Fully multicoated achromatic optics

The objectives and prisms are fully multi-coated. This keeps light transmission high and suppresses internal reflections that affect contrast in bright objects. At this price, you get the aperture and interchangeable eyepiece concept of the top class, without the extra cost of ED glass.

Near the moon's limb and bright stars, a slight color fringe is visible, which is normal for an achromat of this aperture. Anyone who finds this distracting can choose the ED-APO version of the same model.

Interchangeable eyepieces and filter thread

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.

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.

Mounting a tripod

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.

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.

For whom yes and for whom no

• ✓ Deep-sky with two eyes: star clusters, bright nebulae, the Milky Way
• ✓ Observers who already own 1.25-inch eyepieces and filters
• ✓ For those who want an instrument for years to come, with room to grow in magnification
• Handheld or on a light photo tripod: too heavy, too much magnification
• ✗ Traveling with limited luggage space; for this, a 10×50 is more suitable
• ✗ If you are looking mainly low on the horizon, choose 45 degrees
