Telescope HD picture, high light transmittance / good prism / good coating Lens diameter and material, gold magnification, prism material / process, coating process
SMC high-definition coating has high light transmittance and clear imaging this coating is burdy, in order of light transmittance wine red film> green film> blue film, the better the coating, the higher the light transmittance. The clearer the color of the picture
The true 50-caliber light-entry foot picture is brighter, and each optimization effect is both a cost consideration and a breakthrough in the technical threshold; the large objective lens has a wider field of view and the light-entry amount is brighter.
High-definition, low-dispersion ED lenses
Low-dispersion ED lens eliminates chromatic aberration imaging without purple fringing, purple fringing will occur after ordinary glass is refracted; ED lens is better for correcting chromatic aberration
