经纬仪 经纬仪是可把镜筒向水平和上下两个方向自由自在移动的型式。构造和用法都很简单,只是对因日周运动而移动的星星之追踪比较困难,顶操作两支微动杆,否则星星会由视野中跑掉。 经纬仪的使用法与赤道仪不一样, 没有极轴调整的必要,至于星星的追踪方面,把上下、水平微动杆不断地转动, 或者是把天体移至视野边缘,不用微动,让天体本身在视野中移动时紧盯着观测。因为视野在旋转, 所以星野照相不能做长时间曝光

除了小型望远镜喜欢选用经纬仪外,很多天文爱好者也为他们的大型反射望远镜配上经纬仪。我们称呼这种望远镜为「杜布苏尼安」(Dobsonian)式望远镜。 「杜布苏尼安」式望远镜的重量赤道仪的望远镜轻,方便携带到郊外进行观察,而且价钱便宜及可以自己制造。适宜配合广角目镜来进行深空天体观察。

计算机控制经纬仪 由计算机控制水平和上下两个方向的移动来追踪星星。和传统经纬仪一样,没有极轴调整的必要,使用者只须在每次观察前,手动导入2颗参考星,之后你就可以轻松地命令望远镜指向观察目标。使用方便但耗电量大,野外观星时要携带大型蓄电池。 因为视场在旋转, 要用它来作长时间曝光的天文摄影,必须配合视场旋转器度(field de-rotater)使用。

值得提一下,有的简易经纬仪连微动都没有,只有螺丝旋松旋紧,或者像Dobsonian一样靠轴的摩擦力固定

没有用过,应该是随动的,阻尼可以调整,好像不能微调,要靠手感了,优点是比较小巧。。。

这一页的TS-AZ和晶华K系列类似(有微调),两个Giro就没有微调了,你上面的AIM好像也没有微调

号称世界上最轻的经纬台Kenko NEW KDS反而有微调,日本人真是牛啊……
