Description

The world's widest apparent field eyepiece for astronomy, the new 9mm 120° Series Argon-Purged Waterproof Eyepiece, has been extensively field tested by amateur astronomers at star parties in Canada and the USA, and is now in the production stage. What we learned during these tests was that about half of the viewers could see the entire boundary of the field stop at once, while the other half could only see stars as far to the edges that their eyes would permit without seeing a boundary.
