如题，手上有台GP赤道仪，多年前买的，一直不用，现在想用了，查了好多资料，好象是完全弄懂了，只怕纸上谈兵而已，一狠心花时间找GP说明书的相关章节看了，译了几句，水平很差，英语都还给老师了，又不敢独享，传上来，大家将就着看吧！顺便也帮我修改修改。总体感觉GP说明书不够详尽，倭人还留了一手，有空我再写些使用的心得体会吧！
正文如下： Using a Polar Axis Scope in the Northern Hemisphere在北半球使用极轴望远镜 1.
In the Northern Hemisphere, locate Polaris in the sky and Point the Polar axis of the mount in the direction of Polaris.在北半球，从天空中找到北极星并使赤道仪的极轴望远镜指向北极星的方向。 2.
Adjust the tripod legs until the bubble level on the left side of the mount indicates the tripod is level.调节三角架的腿长，直到赤道仪左边的水准泡指示三脚架是水平的。 3.
Install the polar axis scope illuminator onto the front of the polar axis and turn on the switch. (Refer to the paragraph <How to use a Polar Axis Scope illuminator>.)安装极轴望远镜照明在极轴的前端并打开开关。（查阅章节《如何使用极轴望远镜照明》。）
*optional选购
The GPD2 mount comes as standard with the built-in type illuminator.GPD2赤道仪内建照明作为标配。 4.
Unfasten the Decl. clamp and turn the optical tube until it is nearly at right angles to the polar axis. If you do not do this, the polar axis scope will be shaded with the Decl. axis and can not be used.松开赤纬制动钮并转动望远镜镜筒直到它与极轴镜的角度接近直角，如果你不如此做，极轴望远镜将被赤纬轴遮挡而无法使用。 5.
While looking in the polar axis scope, adjust the diopter adjustment ring to focus on the reticle in the field of view.当观察极轴镜时，调节曲光度调节环使视场中的划分板对焦。 6.
Look at a map or atlas that shows the longitude of your observing site. Once you know your longitude, find the difference between that and the standard time meridian for your zone. Set the difference on the time meridian offset scale. If your observing site is located in the east of the standard time meridian, set the E side graduation to the time meridian indicator. If in the west, set the W side graduation to the time meridian indicator.查找地图或地图册上所标示的你观测点的经度，一旦你知道了你的经度，就找出了你所在地点与标准时间子午线的时差。在时间子午线标尺上设定时差。如果你的观测点位于标准时间子午线的东面，则设定时间子午线标尺上位于E这边的刻度。如果在西边，则设定时间子午线标尺上位于W那边的刻度。 7.
Set “0 hour” on the R.A. and hour graduation ring to the R.A. indicator after loosening the graduation-ring setscrew. Re-tighten the graduation-ring setscrew. (The graduation-ring setscrew should be loosened when observing.) 松开定位螺丝后把赤经兼小时刻度环“0小时”位置对准赤经指示箭头。重新上紧定位螺丝。（观测时须松开定位螺丝。） 8.
Unfasten the R.A. clamp and turn the telescope around the polar axis to set the observing date on the date graduation ring to the observing time on the R.A. and hour graduation ring.松开赤经制动钮并使望远镜围绕极轴旋转用以设置日期刻度盘上的观测日期对准赤经兼小时刻度盘上的观测时点。 9.
Look through the polar axis scope and bring Polaris in the Polaris circle of the reticle by adjusting the azimuth and altitude with the azimuth adjustment knobs and altitude adjustment screw. The Polaris circle indicates the correct position of Polaris relative to the celestial pole.调节方位角调节旋钮和调节仰角调节螺丝来设定方位角和仰角使得从极轴望远镜观察北极星处于划分板的北极星圈内。 10.
Owing to a wobble in the earth’s axis, the position of Polaris changes gradually over time. The diagram 10 shows the position of Polaris through the year 2005. In order to align the polar axis more precisely, put Polaris on the position indicated on the diagram.由于存在地轴摆动，天极的位置随时间逐渐改变，图10表示2005年北极星经过的位置，为了更精确地校正极轴，以图示标明北极星的位置。 （译者注：图10略） How to set the Polaris circle to the R.A. and hour graduation and date graduation如何设定北极星圈至赤经兼小时刻度和日期刻度 1.
Incline the polar axis by turning the altitude adjustment screw so that it parallel to the ground.旋转仰角调节螺丝倾斜极轴与地平线平行。 2.
Release the R.A. clamp and rotate the polar axis until the Polaris circle on the reticle is directly below. (Ignore the southern hemisphere reticle.)松开赤经制动钮并转动极轴直到划分板上的北极星圈置于正下方。（忽略南半球划分板。） 3.
Fasten the R.A. clamp.锁定赤经制动钮。 4.
Set “0 hour” on the R.A. and hour graduation ring to the R.A. indicator after loosening the graduation-ring setscrew.
Re-tighten the graduation-ring setscrew. Turn the date graduation ring until October 10th Lines up with 1:20 a.m. on the R.A. and hour graduation ring.(At this time on this date, Polaris is at upper culmination.)
松开赤经兼小时刻度环的定位螺丝后把赤经兼小时刻度环“0小时”位置对准赤经指示箭头。
重新上紧赤经兼小时刻度环的定位螺丝。旋转日期刻度环10月10日的刻度对准赤经兼小时刻度环的凌晨1：20。（是日此时北极星位于最高点。） 5.
Loosen the setscrew that secures the ring with the time meridian indicator. Turn the ring until the time meridian offset scale. Re-tighten the setscrew.松开固定时间子午线指示环的定位螺丝。旋转这个环直到时间子午线偏移刻度。重新上紧这个定位螺丝。 HOW TO USE THE R.A. AND DECL. GRADUATION RINGS (SETTING CIRCLES)如何使用赤经和赤纬刻度环（标尺圈） The R.A. and Decl. graduation rings (setting circles) are helpful to search for faint nebulae and clusters which are hard to be found with the naked eye. To make a search with the graduation rings, you first have to locate a bright star near the object you want to observe. The following is an example on how to use the graduation rings.赤经和赤纬刻度圈（标尺圈）有助于搜寻肉眼难于寻找的昏暗的星云和星团。运用刻度环搜寻，你首先要在你欲观察的目标附近定位一颗亮星。下列一个例子如何使用刻度环。 Example: Finding the Ring Nebula, M57例：寻找环状星云M57 From the star atlas, you will see that the Ring Nebula, M57, is close to the star Vega. Vega is a bright star of magnitude 1 and can be seen from Spring to Autumn in most places. Let’s use Vega as a base to find M57. (The telescope must be polar aligned.)从星图上，你将看到环状星云，M57，临近织女星。织女星是一颗明亮的一等星并且从春季到秋季都能被看到。让我们使用织女星作为基础来寻找M57。（望远镜必须对好极轴。） 1.Find the coordinates (right ascension and declination) of Vega and M57 in a book or star atlas.在书或星图中找到织女星和M57的坐标（赤经与赤纬）
| R.A. | Decl. | | Vega | 18h36m | 39° | | M57 | 18h52m | 33° |
2.Center Vega in the field of view of the telescope using a low-power eyepiece (Under 50X).使用一个低倍目镜（50倍以下）使织女星位于望远镜视场的中央。 3.Turn the R.A. graduation ring and set is to 18h36m (18hours 36minutes).转动赤经刻度环并设定在18h36m（18时36分）。 4.Set the Decl. graduation ring to 39 degrees.设定赤纬刻度环至39度。 5.To have the telescope moved to M57, turn the R.A. slow-motion control knob or drive the R.A. motor until the R.A. and hour graduation ring is set to 18h52m.将望远镜移向M57，旋转赤经微调控制旋钮或驱动赤经马达直到赤经兼小时刻度环设定在18h52m。 6.Turn the Decl. slow-motion control knob or drive the Decl. motor until the Decl. graduation ring is set to 33 degrees.旋转赤纬微调控制旋钮或驱动赤纬马达直到赤纬刻度环设定在33度。 7.The Ring Nebula can now be seen in the field of view. But, it may be very small. Try to use a higher-power eyepiece.这个环状星云现在就能在视场中被看到。但它可能很小。尝试使用一个高倍目镜。 |
