The Celestron Omni Plössl 4mm is a very high powered eyepiece, best used in smaller aperture telescopes. Celestron’s series of Omni Plössls are an economical Plössl design, with fully multi-coated glass surfaces. The edges of the glass are blackened, reducing reflections inside the eyepiece, for better contrast. Omni Plössls are threaded to accept filters and have roll down rubber eye-cups to shield the viewing eye from any light interference. Eyepieces come with plastic caps to keep them protected from dust and moisture, when not in use.
