Most people believe the magnification is the most important thing in larger binoculars, but no matter how magnified the image, if enough light isn't collected by the lens you won't be able to see the image clearly. For more light you'll need a bigger objective lens. This is especially important for celestial viewing. You'll want to collect as much light as possible from distant stars and planets to see greater detail. For astronomical observations we do recommend the binocular's aperture to be at least 50mm. Binocular magnification of 9x or 8x is the best - binoculars with 10x or higher magnification may be difficult to hold steady, but if supported on a tripod or a fence, they will bring the objects even closer. The feedback from our customers has been great - they know they received the best value when buying large objective binoculars from OpticsPlanet.com. Make sure to take a look at our binocular accessories and tripods.
