Had a chance to look through the
Nikon 18x70 Astroluxe recently. To date, no one has yet found an astronomy bino that is perfect all the way out to the edge, but this one is the closest I have seen yet. In fact, things looked so good at the center of the field that I almost forgot to check the edges and if I didn't notice, I promise it couldn't have been too bad. Only when I went searching for distortion did I find any hint at the extreme edge of what I could see. Basically, I'd call this one 95% perfect. Close enough for me.
