    LOA 21mm 3D Eyepieces: 21 mm focal length, 65 degree AFOV, fully multicoated, includes Lederman Optical Array. This beautiful, patent pending invention will carry you into The Cosmos.

    3d eyepiece 21mm

    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!

     3D Eyepieces work in ALL binoviewers used in Telescopes, and most Giant Binoculars such as Vixen, Oberwerk, Lunt and APM. They do  not work in the older Apogee Giant Binoculars which take odd sized eyepieces, not 1.25” Eyepieces.

    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!

    Great 3d binoculars

    Hello. I’m sorry for taking so long to report to you about the Space Walkers, but I have been searching fruitlessly for a dark site for a proper test of them. I found one. They made me and a few others literally gasp at the effect, it was so notable. On that chaise lounge, the Hercules Cluster, “Anybody want to see M 13?”, rang out. Was near the zenith, and that small fuzzy ball definitely appeared set apart from the surrounding background (foreground, I wondered?) of suns.

    EXCELLENT binoculars

    I've been using the Spacewalker 3D's heavily for about four months now. I'm big into amateur astronomy, especially binocular stargazing. I've had the privilege of owning other highly esteemed binoculars, like the Oberwerk 8x40 Mariner, and can say that without a doubt these ones are my go-to. Here's my run down. The image quality easily matches the best binoculars I've tried, but, unlike the Oberwerks, comes in a significantly lighter package. This gives you much longer viewing sessions and makes them very newbie friendly if you want to introduce a newcomer! So, great optics and lightweight. The 3D effect is moderate, but it is enchanting, ESPECIALLY during those warm summer nights when the Milky Way is PACKED with stars. It feels like you're suspended in a sea of brilliant little lights. You can see three transparent squares in the left eye, but honestly, I look at daytime targets with them all the time and it hardly bothers me at all, and these are really meant for astronomy. And finally, they're small enough that you can actually fit them comfortably in the pockets of a decent pair of cargo pants, making it easy for me to bring them ANYWHERE.

    -Excellent optics (very bright and sharp stars)
    -Moderate but beautiful 3D effect
    -Very lightweight!
    -Very portable!
    So, if you're looking for some great binoculars that make an excellent go-to and enchant beginners you want to share stargazing with, I highly recommend you stop your search here. Clear skies to you!
