Historical Review of Swift 804 Audubon Binoculars
Ed, my cheap Nikon Sportstar 8x25 roofs "throw up" better stellar images than these 804R's but the Sportstar daytime images just aren't very clear. Whatever that means, I have no idea... ;-) Actually, what I was getting at earlier is that I believe the SA/astigmatism/whatever issue is... -
