Omegon Zoom Eyepiece Super Pl\u00f6ssl 7-21 mm (1.25 inch): three eyepieces in one twist<\/strong><\/h2>\n\n\n\n

The Omegon Super Pl\u00f6ssl zoom eyepiece continuously adjusts its focal length from 21 to 7 mm. You locate an object at low magnification and then zoom in to the level of detail that the evening permits, without changing eyepieces.<\/p>\n\n\n\n

On a 130\/900 Newtonian, the magnification range from 43x to 129x goes from the entire lunar disk to crater detail with the same focusing movement.<\/p>\n\n\n\n

This is how the field of view of a zoom works<\/h4>\n\n\n\n

The apparent field of view changes with the zoom setting: from 30 degrees at 21 mm to 43 degrees at 7 mm. That is a characteristic of every zoom eyepiece in this class; therefore, at the high magnifications where you need the field the most, it is the widest.<\/p>\n\n\n\n

Practically equipped<\/h4>\n\n\n\n

The foldable rubber eyecup keeps stray light out, and the filter thread accepts moon and color filters that remain functional at any zoom setting.<\/p>\n\n\n\n

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

A strong first upgrade alongside the included eyepieces of a beginner telescope: a single purchase covers the complete magnification range. An Omegon moon filter screws directly into the filter thread.<\/p>\n\n\n\n

For whom yes and for whom no<\/h3>\n\n\n\n
