(I wanted you to know now in case it takes a while for him to answer.) Another term that is often used here is the "sweet spot." It is where the image is sharp and acceptably sharp. In the binoculars he cites, the sweet spot covers only about the inner 50% to 60% of the overall field. Outside of that the image you see will be fuzzy and/or distorted. You might be unhappy with that, day or night. Binoculars that feature a wide angle with a large sweet spot generally cost more because it takes extra engineering and well-designed lenses to correct the outer distortions.</p></blockquote><p></p>
