Product Highlights
  • 52° Apparent Field of View
  • 6mm Eye Relief

If you're looking for a higher quality eyepiece than the standard-issue offering that come with most telescopes, the 4.0mm Omni provides more enhanced features at a great value.  Celestron designed the 4.0mm Omni with attention to the details that separate good eyepieces from average ones.  It is a 4-element Plossl formula with blackened lens edges, multilayer coatings upon each surface and an anodized barrel.  These features combine to increase contrast and light transmission, and of course it is threaded to accept Celestron's many 1.25" eyepiece filters.

Eye Relief 6.0mm
Apparent Field of View 52°
Dimensions 1.3 x 2.1" (34 x 53mm) WxH

              I thought it was going to be harder to find stars and objects with this eyepiece but found it to be much easier. Diffenently recommend it.

                I have a Orion 4,5 inch appeture 900 mm telescope and this eyepiece gets me 225X magnification. The eye relief is comfortable and the field of view is adequate.
