Omegon LE Planeten 3 mm Oculair (1,25 inch): planeetoculair met 20 mm oogafstand<\/strong><\/h2>\n\n\n\n

Het Omegon LE Planeten 3 mm is een planeetoculair met zeven lenselementen, een beeldveld van 55 graden en een royale oogafstand van 20 mm. Het kortste brandpunt van de serie, bedoeld voor maximale vergroting bij een rustige atmosfeer.<\/p>\n\n\n\n

LE stands for long eye relief: the series is designed for relaxed viewing at high magnifications. The eye relief of 20 mm remains the same across the entire series, so switching focal lengths does not require getting used to a different viewing position.<\/p>\n\n\n\n

Built for Contrast<\/h4>\n\n\n\n

Seven lens elements with multi-layer anti-reflective coatings and a design that minimizes stray light: this results in a dark sky background and high contrast on planetary disks and the Moon.<\/p>\n\n\n\n

The image is free from the kidney bean effect, the black shadow that appears with many eyepieces when your eye is not precisely on the axis.<\/p>\n\n\n\n

20 mm interpupillary distance<\/h4>\n\n\n\n

With a 20-mm eye relief, you can use the binoculars while wearing glasses without losing any field of view. Even without glasses, the view is comfortable: you don't have to press your head against the eyepiece.<\/p>\n\n\n\n

The 1.25-inch barrel has filter threads for moon and color filters.<\/p>\n\n\n\n

Wat zie je met 3 mm?<\/h4>\n\n\n\n

Op een telescoop met 650 mm brandpuntsafstand geeft 3 mm een vergroting van 217x, op 900 mm al 300x. Reserveer die vergroting voor telescopen met voldoende opening: realistisch is maximaal 2x de opening in millimeters.<\/p>\n\n\n\n

Bij goede omstandigheden zie je fijne structuur langs de maanterminator, de Cassini-scheiding en nauwe dubbelsterren.<\/p>\n\n\n\n

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

The LE series ranges from 3 to 18 mm with the same field of view, so combining focal lengths as a set works well. An Omegon moon filter (1.25 inches) reduces the brightness of the moon\u2019s image; an Omegon Barlow lens doubles the range of the longer focal lengths.<\/p>\n\n\n\n
