Product Description
This fully-multicoated eyepiece is one of the shortest focal length and most economically-priced Plössl eyepieces available. It's designed for very high magnification lunar and planetary observing and for splitting close binary stars. The field of view is surprisingly wide when compared with other Plössls in this focal length range. A soft rubber eyecup on the titanium-colored body shields the eye from ambient light. Its very short eye relief will severely vignette the field of view for eyeglass wearers. We can't recommend this eyepiece for those who must wear glasses while observing. Plastic caps are supplied to keep both ends of the eyepiece dust free.

I bought this as a compromise to use w/ both my scopes, an Orion Star Blast 6/6i & my overpriced Tasco Spacestation 70mm Refractor. Unfortunately , the 70mm just doesn't catch enough light for this 4mm eyepiece.
OTOH, my Orion does work pretty well w/ this eyepiece, giving it's best views of Saturn yet.
Overall, I'm satisfied w/ this Celestron Omni Series 4mm Eyepiece. For the price, I think this is a great addition to my Orion, it gives a medium-high power view. Now if I could find a high power eyepiece I can afford. (Posted on 8/26/2019)

Hi guys. Today i want to tell you about this product. First of all, I have a bad telescope. But, with this eyepiece, it let me see Saturn, Jupiter, a little bit of Uranus and Venus, the moon, and Neptune. But Pluto was so little and white because my telescope is not so good but your telescope might be perfectly fine. Trust me. (Posted on 8/4/2017)
