Well, finally had a good opportunity to really try these out... the weathers just not allowed a real trial until tonight. I'm very happy with them, they do exactly what I was wanting- to aid naked eye observation, with as wide an angle as possible. The focus goes fuzzy at the edges, but that's not a problem to me... the center area is plenty adequate, which is where you're concentrating anyway., so it's only noticeable if you look for it... at least for me. As a for instance, for me- Andromeda Galaxy is not naked eye for me here where I live... wether it's the skies or just these old eyes, I'm not sure- but it popped right out in these Miyauchi's, though. I love 'em! Wes
