Eyepiece Celestron Omni Plössl 50°

The Celestron OMNI eyepieces offer entry-level optical quality with a 50° apparent field of view and a Plössl-type optical assembly. Lightweight and compact, they are also suitable for use with binoculars.

With anti-reflective coating applied to the lenses, they deliver clear and contrasted images, especially in the center. Each lens of the eyepiece (4 in total) is rimmed with black to limit the appearance of any parasitic light.

Their 50° apparent field of view allows you to keep a celestial object observed in a non-motorized instrument sufficiently in view.

The eye relief of the OMNI 6 mm eyepiece reaches 5 mm, meaning that the image remains comfortable up to a distance of 5 mm above the eyepiece.

With a focal length of 4 mm, this eyepiece is particularly suitable for observing objects with small apparent dimensions (planets, Moon, planetary nebulae...) at relatively high magnification (166x on an optical tube with a 1-meter focal length).

The interior of the eyepiece is threaded with M28.5 x 0.6 mm to screw in filters with a diameter of 31.75 mm (1.25 inches). Among others, interference filters of type OIII, UHC, H-Beta... are used to enhance contrast on numerous nebulae.
