If you use Bino Vue with any of our telescopes for terrestrial viewing, you will enter a new world of visual experience. And, whether you're viewing in daylight or at night, you will hardly realize that each eye is seeing less than 50% transmission normally seen at the same magnification. The reason is that the resolution and contrast are so high and two eye viewing seems to "recover" some of the light loss. Indeed until you go to very high powers, you may prefer these views with seemingly darker sky backgrounds. The 2x Amplifier/Corrector eliminates prism aberrations (spherical, color, and edge of field astigmatism). The faster the system the greater the need.The Bino Vue with 2x corrector can be swapped into a focuser without need to refocus.
