佳能电子望远镜 Canon15x50IS
Canon 15x50IS image stabilization telescope has excellentperformance. It is a high power mirror with moderate price in Canonimage stabilization series: VARI-ANGLE PRISM (VAP) imagestabilization device. It uses precision gyroscope to detect theslightest movement and a special prism controlled by microprocessorto correct the refraction angle of incident light.
Lead-free Ultra-Low Scattering (UD) Lens: In order to improveoptical performance, the telescope uses UD lens developed by Canonto effectively eliminate chromatic aberration (a rainbow-shapeddistortion) and bring clear images with super bright and highcontrast.
Super-spectral coating: All lenses are coated withsuper-spectral coating, eliminating ghosts and flickering, ensuringvivid and sharp images, color balance. Canon's unique DOUBLET FIELDFLATTENER technology guarantees the sharp and smooth imaging of thewhole field of view. It can be e with 58MM filters andall-weather products.
适用范围:出游,观鸟,观星,演唱会,体育赛事,车船上观景,等等。
使用高倍望远镜的麻烦是他们把什么事情都放大了,甚至Zui轻微的移动和晃动。比如拿望远镜的手的轻微的颤动。放大倍率越大,微小的颤动被放大的就越大,造成眼睛的疲劳和效率的降低。当观察者站在静止的地面上时,这种晃动已经几乎不能忍受。想象一下,如果观察者是站在车上,船上,飞机上时,问题的严重性时多么的大。这时候,即使我们把望远镜装到三角架上,也不能消除晃动地影响。
这时候,如果您有一台电子稳像望远镜,一切问题都解决了。
