双星体

Using the K20 eyepiece included as standard equipment, about 45x magnification, it's easy to see the Andromeda Galaxy and its smaller satellite galaxy M32. When compared to 60mm refractors, the Powerseeker 114 brings out much more detail in the Orion Nebula, reveals many more stars in Perseus' Double Cluster and even brings out a few individual stars in globular clusters like M13. Saturn looks quite small at 45x with the K20 eyepiece, but using my own 7.5mm eyepiece (120x) I can easily detect the shadow cast by the planet on the rings, and even glimpse the ring's Cassini Division. When the mirrors are properly lined up or "collimated," the images are reasonably sharp up to magnifications of 225x.

使用标准配件中的K20 目镜，可以得到45倍放大率，这时候很容易看到仙女座星系，还有较小的星系M32；和60毫米口径的折射望远镜相比，114 EQ可以看清更多猎户座星云的细节；瞄准英仙座双星团，看到的星体数量更多，显得更加壮丽；对于球状星团，比如M13，甚至可以显出其中少数独立的恒星；在K20 目镜下（放大45倍）的土星显得相当小，但换成我自己的7.5毫米焦距的目镜(得到120倍)，可以轻松的看到光环在土星上的投影，甚至可以瞥见土星光环内的卡西尼缝隙。

A six-wheeled space exploration robot with active configuration function is proposed.

建立了轮式星体探测机器人的抗倾覆性评价模型，对六轮摇臂星体探测机器人和双曲柄滑块探测机器人的抗倾覆性进行分析和比较，提出一种提高自适应悬架机器人移动性能的措施和方法，实现了一种可主动配置的六轮摇臂星体探测机器人。

But you'll probably need binoculars and a detailed sky chart to see Uranus, a world that lies some 20 times farther out from the sun than our planet Earth does.

但是可能的话，你应该用双筒望远镜和一张详细的星象图来观测天马星，一个距离太阳是我们地球和太阳距离20倍的星体。
