Sea Tidbits: binoculars for astronomical observations should choose the larger diameter telescope, so you can see more objects. So whether it is the bigger the better magnification it? No. Select the magnification to be determined as required observations. When the same caliber. With higher magnification telescope can see more stars what brand of good, but for planar celestial nebula like it, at low magnification look brighter than those at high magnification. Taiyuan sea Tidbits: multilayer antireflection coating material is magnesium fluoride. Single-layer antireflection coating is only a specific wavelength of light have the best antireflection effect on other wavelengths of light AR less effective, it allows each of the surface light reflection to 1.5%, such as for binoculars all surfaces of the telescope price, the light transmittance of more than 80%. Good reflectivity multilayer film of each surface of the light is only about 0.25% for all surfaces such as binoculars, a light transmittance of 90% to 95%.
