Celestron Omni 4 mm: high magnification for the Moon and planets in calm air

The Celestron Omni 4 mm is a classic Plossl eyepiece with four fully multi-coated lens elements. The lens edges are black to reduce internal reflections, resulting in a contrast-rich image with natural colors.

With a focal length of 4 mm, you get the highest magnification from the Omni series. Use this eyepiece on clear nights with stable air for lunar craters, Saturn's rings, and Jupiter's cloud bands.
