赤道仪

一个可以有相当赤经追踪精确度的摄星用赤道仪。

A photographic equatorial mount capable of reasonable accurate tracking of the RA-axis .

而且你已经了解了一些巴洛镜和赤道仪的知识

And you have already studied something about Barlow Lens and Equator Mounts

以上方法是为摄星赤道仪开发的，但任何赤道仪都可使用。

While the technique has been developed for astrophotographic mount , it can be used on any equatorial mount .

本文给出1981.10-1984.12期间，在上海天文台佘山站，用40厘米赤道仪观测得到的117对目视双星的结果。所用的目镜放大倍率为600倍或700倍。

The data of 117 pairs of visual double stars are presented , which are got with the eyepiece micrometer of the 40 cm astrograph during 1981.10-1984.12 at Zo-Se .

赤道坐标系统在显示天球某一天区很有用，对有装了赤道仪的望远镜的观测者非常重要。

RA / dec coordinates are most often used for " finder charts " showing a relatively small area of the sky , and are extremely useful for equatorially-mounted telescopes .
