The problem is most manufacturers don't publish their binoculars transmittance levels, that is unless they are sure that it outperforms their competitors! So how can you be sure that the binoculars that you get have a high level of transmittance? Celestron's SkyMaster line of large aperture astronomy binoculars offers exceptional performance at a great price resulting in excellent value for money. They are ideal for long-distance terrestrial encounters as well as providing a spectacular view of the heavens. So, buying these Celestrons means also buying a tripod and maybe a counter-weighted arm. But the binoculars are ready when you do: A solid-feeling reinforced metal bar forms a keel, from the objective lens covers at the front to the bulbous prism warts towards the rear. A built-in tripod adapter slides along this spine; a knurled knob tightens the adapter down at your preferred position. And when your observing night is over, the bar makes a comfortably grip-able lifting fixture; which you've likely set at the natural balance point. So you can one-hand these heavy beasts into their protective case. As light travels through a binocular, a certain percentage of that light is lost through absorption and reflection at each air-to-glass surface or inside the prism system itself. The amount of original light available to the observer by the time it exits the eyepiece will vary from as low as 50% to as much as 97%. Only the Celestron allows the proper balancing of the gravity center of the bino on its tripod adapter without limiting the IPD adjustment to below 60mm.

The Argus wins by a certain margin with its compact dimensions, light weight and superior optics.
