The Earth Centered Universe (ECU) Pro V6.1 is a planetarium and telescope control program capable of simulating most of the phenomenon of the Earth's sky. Designed for the demanding requirements of an observing amateur astronomer, it also provides extraordinary accuracy as a planetarium program for the "armchair" astronomer or any other person interested in learning about astronomy. 以地球为中心的宇宙（ECU）Pro V6.1是一个天文馆和望远镜控制程序，能够模拟地球大多数天空现象。 它是专为观察业余天文学家的苛刻要求而设计的，它还为“扶手椅”天文学家或任何其他对天文学感兴趣的人提供的天文馆程序，提供了非凡的准确性。Highlights:Known for its ease of use, rich feature set, high-accuracy, and lightning fast speed.Includes extensive databases such as the Hubble Guide Star Catalog; the detailed, amateur oriented, SAC deep sky database; the huge Principle Galaxy Catalog; the General Catalog of Variable Stars; the Washington Visual Double Star catalog; a dedicated planetary nebulae database; the Sun and Moon; the planets; 700,000+ asteroids (downloaded from Lowell Observatory); and add your own comets, asteroids and tens of thousands of your own objects too.Comprehensive control of most computerized telescopes on the market (even many discontinued ones too). Interfaces to many telescopes and mounts natively, but also supports the ASCOM Inititive's telescope and focuser "drivers".High quality printed star charts.Written by an observer for observers.Written by a CCD imager for imagers.Powerful animation mode.A large detailed up-to-date User's Manual with context sensitive help. Included and Supported Databases:The Yale Bright Star Catalog (9,100 stars to magnitude 6.5) - included are many "common" names for the bright starsThe SAO Star Catalog (about 250,000 stars to magnitude 9.5)The Tycho-2 Star Catalog (about 2,500,000 stars to magnitude 12-13)The Hubble Guide Star Catalog (about 15,000,000 stars to an average magnitude of about 14)Support is provided to read the US Naval Observatories A-2.0 (~500,000,000 stars!) and SA-2.0 (~50,000,000 stars)The Saguaro Astronomy Club deep sky database (V8.1) which contains 10,342 objects of all types, including of course the Messier CatalogThe Principle Galaxy Catalog (2002 edition - about 1 million galaxies)The General Catalog of Variable Stars (September 2015 version - 52,011 stars)The Washington Visual Double Star Catalog (2016Mar25 version - 135,098 pairs of stars)The Wallace-SEC galactic planetary nebulae database (V7 - 1143 objects)The Lowell Minor Planet Database (over 700,000 minor planets). This database is updated from within ECU over the Internet.Enter the orbital elements for up to 10,000 comets and minor planets (asteroids) (comets and asteroids can be automatically downloaded from within ECU from the International Astronomical Union's Minor Planet Center)The eight planets (and Pluto!), the Sun, Anti-Sun, and the MoonAdd up to 50,000 of your own objects Main Features:ECU is lightning fast compared to many other astronomy programs and runs very well on older computers that you might use in the field (e.g. older laptops).ECU is very easy to use. Most operations are performed with the mouse. A "toolbar" is provided for most common functions and for those who prefer to use the keyboard, there are many hot-keys.The sky can be drawn as either in Sky Atlas (north is up) mode, Local Horizon (up in the local sky is up) mode or with the sky rotated at any arbitrary angle.It exhibits a colorful display - the colors of all screen elements are controllable by user. Fonts can also be set.High quality star charts can be printed (in black and white and in full color) which are highly customizable by the user including titles, legend, fonts, and border dimensions. You can also print two charts per page at different zoom levels.ECU status displays include the local time, universal time, latitude and longitude, RA/DEC, AZ/ALT, field size, magnitude limits, sky darkness, hour angle, sidereal time, and Julian date.Stars can be drawn in color based on either their spectral type or B-V color index.Deep sky objects are drawn their correct size, shape, and orientation (when this information is included in the database).There is advanced control over magnitude limits for all types of objects.Clicking on an object causes an information box to pop up. All objects provide their RA, DEC, azimuth, altitude, rise and set times, magnitude (if known), air mass, extinction, galactic latitude, and galactic longitude. Other information provided is as follows:The Sun: distance in AU, kilometers, and light travel time; angular size; solar longitudeThe Moon: distance in kilometers; angular size; phase angle; phase age in days; its illuminated fraction in percentThe planets: distance in AU, kilometers, and light travel time; angular size; phase; rates of motion; ecliptic latitude and longitudeComets and asteroids: distance to the Sun and the Earth in AU, kilometers, and light travel time; solar elongation; phase (for asteroids); rates of motion; ecliptic latitude and longitudeYale stars: Yale number; HD number; SAO number; Flamsteed/Bayer designation, color (B-V); spectral type; proper motionSAO stars: SAO number; spectral typeTycho-2 stars (when information is available): Tycho-2 number, Hipparcos number, HD number, magnitude (B and V), proper motion, and parallax (with error estimate)Hubble Guide Stars: GSC catalog number; estimated position error; magnitude band; Plate IDSAC deep sky objects: a varying amount of information, but usually their name (and alternate name); Dreyer description, angular size; position angle; object class; notesPGC galaxies: the primary and up to four other names; morphological type; angular size; position angle; object class; radial velocity; implied distance in light yearsVariable stars: minimum and maximum magnitude; designation; type of variability; period; rising time (or duration of eclipse); time of previous maximumDouble stars: combined magnitude of the pair; discoverer code; DM number; magnitudes of both stars; separation and position angle at up to two dates; spectral typeUser objects: user number; text descriptionThe user can display up to 50 images of an object.The user can add observing notes about any object.The user can measure angular distances and position angles on the sky with the mouse. Several angular formats are provided.All user settings can be saved to named configuration files for later retrieval. Comet and asteroid elements can be saved to or loaded from separate ASCII files.The time can be set as local mean time, UTC, Julian Date, or from the computer's clock (local or UTC). Dates can be entered from 4713BC to 9999AD. For Canada, US and Europe Daylight Saving time can be automatically set.The observer's location is entered by latitude and longitude or from a list of cities (add your own, too).Sync your time and/or location using a GPS receiver.The effects of observer's parallax, nutation, precession, light travel time, aberration, and atmospheric refraction can be individually controlled.The sky can be displayed as white on black or black on white, or, of course, in full color. Special "night vision" modes protect your night vision when ECU is used in an observatory.ECU displays the horizon line, custom horizon lines set to match your observing sites, ecliptic line, meridian line, RA/DEC grid (auto scaling), Local Horizon grid (auto scaling), constellation lines, boundary lines, galactic equator line, etc.Extensive text labels are provided for all types of objects. Text labels can be intelligently placed to avoid overlap.Several field "targets" of programmable angular size, including rotatable rectangles, can be drawn to represent the field of view of your main telescope and finder scope respectively. You can place up to 100 of these "targets" anywhere on the sky.The user can center the display at any RA/DEC, AZ/ALT, Hour Angle/DEC, bright star, constellations, Messier object, named deep sky object, point on the horizon (north, south, etc.), or solar system object.The object databases can also be extensively searched.Powerful tools to search and filter comet and asteroid elements by brightness, sky position, visibility, Earth distance, etc.Create detailed reports (that you can import into a spreadsheet or database program such as Excel) of objects plotted on the screen or on printed charts.ECU's animation mode allows time increments from 1 second to four years. The display can be "locked" to the Sun, Moon, a planet, a comet or asteroid, an AZ/ALT or an RA/DEC. Trails of objects with time labels can be drawn.A dialog box to display the rise/set times of the Sun and Moon on the current day is provided. It also shows the times of civil, nautical, astronomical twilight, the phase of the Moon, the length of the day and night, and the length of nautical and astronomical darkness. 新功能介绍 “以地球为中心的Universe Pro”的V6.0L和V6.1之间的变化更新的用户界面 ECU是仍在积极开发中的最古老的天文馆和望远镜控制程序之一-最早于1992年3月推出！ 以前的（pdf）用户手册已替换为上下文相关的在线帮助（网站上提供了pdf版本，供希望打印的用户使用）用户手册也已在多个领域进行了扩展和改进。此版本通过减少菜单项和对话框的数量极大地简化了用户界面（不会丢失任何重要功能！）现在，大多数对话框都是“选项卡式”，将相似的设置和功能保持在一起（例如，所有时间和设置都在一个对话框中）这些更改很多，因此下面不再单独列出现在，所有对话框均已重新设置样式，具有更现代的外观一些重要的对话框-对象搜索和动画-不再是“模式”对话框，因此在执行其他操作时可以保持打开状态现在，许多对话框都有“应用”按钮，因此可以在不关闭设置的情况下进行设置更改除了默认的“ Windows”样式外，整个应用程序还可以设置为36种“样式”之一。这些样式会影响外观，字体和颜色。兼容性 ECU兼容： Windows XPWindows Vista（32和64位）Windows 7（32位和64位）Windows 8和8.1（32位和64位）Windows 10 天空图/打印功能 用于绘制天空的地图投影已被完全修改。它如何使用更好的立体投影。现在，它可以更好地以大图表形式表示对象形状，但会扭曲比例尺（一切都是妥协！）添加了反禅定点（最低点）当显示用户对象的大小时，现在包括小数点太阳符号更具特色资料库 变星综合目录数据库已更新至当前版本（2015年9月），现在包含52,011颗恒星。它的存储分辨率也有所提高华盛顿视觉双星数据库已更新至2016Mar25版本，现在包含135,098对双星现在，以更高的分辨率存储和绘制用户对象在任何给定时间可以活动的彗星/小行星轨道的数量已增加到10,000对象搜寻 现在将对象搜索和“对象列表”功能统一到一个选项卡式对话框中现在，您可以搜索常见的对象名称，例如“ Ring Nebula”搜索小行星和彗星比较容易-现在您可以按名称，数字（例如“（xxxx）”）和按名称（例如“ C / 2005B1”或“ 194P”）查找小行星。自动化接口 ECU现在包括Windows COM对象接口（类似于ASCOM驱动程序的工作方式），该接口允许外部程序访问和控制ECU。该功能目前受到限制，主要是为了通过外部程序访问ECU的内置对象数据库及其一些天文计算而开发的。目前，它具有大约30种可用的属性和 新杂项功能 会自动读取ECU的3.0、3.1、3.2、4.0、5.0和6.0版本的配置文件，并将其转换为V6.1格式。此操作是完全透明的添加了大气压和温度设置-它们会影响折射计算地理位置对话框可以在Google地图上显示当前位置允许按十进制度或度和分输入纬度和经度一些重复的计算已经并行化，因此将利用多核或多核处理器系统颜色（用于夜视模式）无法再更改-较新版本的Windows不允许使用现在可以设置状态行的行和文本的颜色现在，星期几显示在“日月数据”对话框中目录/文件/ Web设置对话框：添加了浏览按钮，使文件和目录的设置更加容易现在具有用于显示ECU的Documents和AppData目录（用于存储文件）的按钮用户对象文件现在用分号分隔，可以使用文件浏览器轻松选择在“识别对象”对话框中，现在显示对象的“时角”字段菜单现在称为图表菜单字段目标现在称为图表目标某些键盘快捷方式已更改现在，在“状态行”上单击鼠标左键即可启用/禁用滚动条（而不是显示/隐藏“状态”框）加载新的配置文件（对于ASCOM型望远镜）不再禁用望远镜界面与加载/删除“哈勃指南星”目录相关的功能已删除-现在由程序安装程序处理用于估计星系距离的哈勃常数已减小至70。现在，在“输入时间”对话框中，“日月升起”和“设置”按钮将使用指定的日期，而不仅仅是当前日期。Bug修复 启用“ Only Messiers”时绘制SEC行星状星云修复了与保存轨道文件有关的错误现在，它会在启动时执行更多数据库检查，并且如果检测到问题，则会显示更多有用的错误消息修复Hipparcos星搜索-错过了每个区块中的最后一个星修复“识别对话框和对象报告”中的可变星数据的格式校正消息以获取可变恒星预测的最大和最小亮度（以前，当日食双星实际上是最小值时，它报告的最大值）修复轨道望远镜的错误修复/改善望远镜的视场图修复丢失的默认图表目标矩形Operating System: Windows XP, Vista, 7, 8/8.1, 10 Home Page - http://nova-astro.com/
