Celestron Omni 4mm Eyepiece

For higher-power viewing with a compatible telescope, the Celestron Omni 4mm Eyepiece brings a premium Plossl optical layout in a compact 1. 25-inch format. Its 4mm focal length is paired with a 4-element symmetrical design, making it a strong addition for observers refining their setup with a shorter focal length eyepiece.

Multi-layer coating on each lens surface supports light transmission and contrast, while blackened lens edges help reduce internal reflections. Celestron also applies a two-step anodising process to the top eyepiece barrel to limit unwanted reflection. Practical details are equally well judged, with fold-down rubber eye cups and a rubberised grip for more secure handling during use.
