信达Sky-Watcher 系列的牛顿反射式望远镜全部采用抛物面主镜,中央像质锐利,改善了球面镜边缘像质肥大的问题,此系列的反射镜均采用了铝介质镀膜,比传统镀膜的反射镜耐用性高,此系列抛物面镜面反射和所有DOB机型采用了四臂中央副镜支撑( 0.5毫米厚) ,以减少衍射峰值和减轻光损失。
主要参数:
Diameter/Aperture: 150mm -口径:150毫米 - Focal Length: 1200mm -焦距: 750毫米
- Aluminized and overcoated mirrors -光学主镜铝介质镀膜
-Diffraction-limited secondary mirror support 中央像质衍射较低
- Paraboloidal (parabolic) primary mirror - 抛物面主镜
- 6x30 achromatic finderscope for easy location of objects -光学寻星镜 6X30,容易定位
-150mm primary mirror collects 33% more light than 130mm, revealing more space treasures with better resolution and brighter image. 150mm口径,集光力比130口径高33%以上,比114口径高73%以上,将提供更大的效果空间与更好的星点汇聚力和更美好的影像。
- Smooth 2" focuser -平滑2英寸无齿调焦座
- 150 primary mirror collects enough light to reveal a wealth of celestial objects - 150主镜集光力强,可观测较为丰富的天体细节
-Short focal length design, ideal for astrophotography 超短焦距的设计,天文摄影理想。
Four-arm, secondary-mirror bracket with fine supports 四臂副镜支撑
The Sky-Watcher paraboloidal (parabolic) mirror reflectors and all Dobsonian models feature a four-arm, secondary-mirror bracket with fine supports (0.5mm thick), to reduce diffraction spikes and light loss.
