    LOA 32mm 3D Plossl Eyepieces: 32mm focal length, 50 degree AFOV, fully multicoated, includes Lederman Optical Array. This beautiful, patent pending invention will carry you into The Cosmos at very low magnification.

    While the trend in the astronomy industry over the last 40 years has been to provide observers with larger and larger apparent fields, Russ Lederman has approached this quest in a totally new and original way. You will experience an exponential leap when it comes to feeling like you are out there, among the stars and nebula!

    The 32mm 3D Plossls have are made with 4 fully multi-coated optical elements and provide exquisite low power views. Ideal for Dobs with no drive since the magnification is very low and objects appear to move very slowly. But these work great in ALL telescopes too!

    3D effect better than expected!

    Even after doing extensive research into the effect these eyepieces have in making a 3D experience, I was astonished at how it made me feel like I was among the stars. A genuinely new aspect to my favorite hobby and I would recommend these eyepieces to anyone interested!

    L-O-A Review. Great optics!

    The LOA-21s and the new technology they introduce to astronomical observing has provided that long awaited next leap I have been eagerly looking for in visual astronomy. Instead of the normal litany of either larger apertures or larger apparent fields of view, for the first time in decades we now have a fundamental and dramatic improvement for visual observing. And while not suited for all celestial observing tasks, the LOA-21s are a transforming experience for the vast majority of celestial targets such as galaxies, nebula, doubles, open clusters, globular clusters, and even rich field scanning. Not being much of a wide field aficionado before the LOA-21s, with them I now find myself going off target all the time to be immersed in the 3D nature of just about any star field in the universe. The observing experience the LOA provides is so different from what I am used to with traditional eyepieces, even ones with apparent fields of view over 100 degree, that I now feel like I am seeing for the first time the many objects I have visited these past 45 years as an amateur astronomer. The views provided by the LOA-21s are natural, intuitive, and filled with the perspectives I see in everyday life; they make astronomical observing new and exciting again!
