星表

Caption:: A sixth magnitude globular cluster in the constellation Canes Venatici, this ball of 500,000 stars is approximately 160 light years across and 100,000 light years from Earth.

这个星团叫 M3，是梅西尔星表的第3个成员，它位於猎犬座，是一个球状星团。

It is currently not possible to use other star catalogs.

目前还不能使用其他的星表。

Note: The UCAC 2 covers the sky from the south celestial pole up to a declination of about 45°.

注意：UCAC 2星表只覆盖从南极到赤纬45度的范围。

These changes are mainly for the following reasons: With the Earth Observatory plate movement; Earth deformation; station plumb line changes; station external conditions, weather conditions change; instruments and observer error, as well as stars form stellar declination, on their own, the annual optical aberration constant and nutation constant errors.

这种变化主要由于以下几种原因：观测站随地球板块的运动；地球形变；测站铅垂线的变化；测站的外界条件、气候条件的变化；仪器和观测者的误差以及星表的恒星赤纬、自行、周年光行差常数和章动常数的误差。

The best "city planetaries" in Ling's list that are larger than 15 arcseconds across and brighter than magnitude 10.0 are not widely known: NGC 1535 in Eridanus, NGC 3242 in Hydra, and NGC 6826 in Cygnus.

在林的星表中，最佳的"城市行星状星云"是大于15弧分、亮于10等的，鲜为人知的：位于波江座的NGC 1535，长蛇座的NGC 3242和天鹅座的NGC 6826。

These are unevolved, slowly rotating non-active stars from a CORALIE catalogue.

这些都是来自CORALIE星表中演化稳定、低自转率、非活动性的恒星，它们已被高精度光谱仪跟踪了很长一段时间来确定其是否拥有行星系统。

So I thought that it will be good to have a simple to use tool to allow amateur astronomers to do plate-solving(detect and match your image against star catalogs), so they can explore and learn more about these marvelous images so I started to develop this project.

于是我在2004年开始了这个工程。我觉得如果有一个简单易用的工具，能够根据星表分析爱好者的照片，那就太好了，我们就可以从漂亮的照片中学习和探索更多的知识。

E., two-catalogue systemes can be joined by reassessing the values, of the quantities of K and △D.

即利用重新确定量K和ΔD的数值来达到两个星表系统的联结。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。
