Celestron Omni Series 56 mm Plossl Eyepiece 2 inch

Deep-sky eyepiece for long-focus scopes

The Celestron Omni 56 mm Plössl is a 2-inch barrel eyepiece built for amateur astronomers and seasoned stargazers who want wide-field views of large deep-sky objects. Its four-element, fully multi-coated optical design delivers sharp, high-contrast images with a 47° apparent field of view. A generous 52 mm eye relief makes extended observing comfortable, even for eyeglass wearers.

Ideal for nebulae and clusters.

This eyepiece suits observers who prioritise expansive, low-power vistas of star clusters like the Pleiades, nebulae such as the Lagoon and Orion, and galaxies including Andromeda. Buyers who need higher magnification for resolving planetary surfaces or tight double stars should look at shorter focal-length eyepieces instead.

Verify your focuser accepts 2-inch barrels

Before ordering, confirm that your telescope’s focuser or diagonal accommodates a 2-inch barrel diameter. The eyepiece is crafted for scopes with longer focal lengths, such as Schmidt-Cassegrain and EdgeHD models, so check that your instrument’s focal length matches the low-magnification, wide-field intent of this optic.
