Celestron's Omni 4mm Eyepiece is designed for comfortable near and deep-space astronomical observation. It is engineered with a 4-element lens configuration, blackened edges, and anti-reflective fully multi-coated optical surfaces to ensure bright and clear high-contrast images with true color transmission across the entire 50° field of view. With a 1.25" diameter barrel, it will fit the most common size drawtubes, visual backs, and accessories. The housing is made of a lightweight and durable aluminum alloy with a reflection-limiting matte anodized finish, and a fold-down eyecup make this eyepiece ideal for comfortable viewing for extended periods with or without eyewear.

    Rated 1 out of 5 by from Not what I spected the ocular size is so small not even a fly can look thru

    Rated 4 out of 5 by from Not bad for the price 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.

    Rated 4 out of 5 by from I would recommend this product Pushes my 660mm refractor to 165x. Eye relief is very short and I can only see about 60% of the eyepiece field. That's ok for planetary viewing. Optical quality is good.

    Rated 5 out of 5 by from Amazing Eyepiece 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.
