The Celestron Omni Plossl 1.25 inch Eyepiece is not only a very impressive device to use with a telescope because of the quality of its components but it also looks so good that its quality is self-evident.

The matte aluminium barrels and the blackened lens edges are not only attractive but very functional as they reduce the likelihood of reflections and glare on the exterior and reduce reflection and increase contrast on the interior.

The four-element Plossl optical design is another impressive feature and the 1.25-inch barrels are threaded so that they can accept filters.

The rubber eyecups increase the contrast but they can be folded down for users who wear spectacles.
