Edit / Find...   ()

Summary

Finds a specified object in the active window.

Description

When you select this command, a small dialog will be displayed inviting you to type or select the name of the object that you want to find. If you accept the dialog, AstroGrav will find and select the requested object if it exists, and if necessary scroll the window to make it visible. In the case of a view window, the window will be scrolled so as to position the found object at the center of the window.

In a view window of a solar system simulation, there are also the following four options.

• Star allows you to search for a particular background star.
• Constellation allows you to search for a particular constellation.
• Right Asc/Dec allows you to search for the point with a particular right ascension and declination.
• Azimuth/Altitude allows you to search for the point with a particular azimuth and altitude, with this option only being available when viewing from a location on an object (such as the Earth).

As in the case when an object is found, the view window will be scrolled so as to position whatever has been found at the center of the window. Searching for a background star or constellation works regardless of whether or not background stars or constellations are currently shown in the window. Searching for a particular point works regardless of whether or not the appropriate grid is currently shown in the window.

Background stars can be searched for using any of the following names, catalogue numbers, or designations.

• Common Name : for example Sirius
• Harvard Revised No : for example HR 2491
• Flamsteed Designation : for example 9 Canis Majoris or 9 Canis Major or 9 CMa
• Bayer Designation : for example Alpha Canis Majoris or alp Canis Major or alp CMa
• Durchmusterung ID : for example BD-16 1591
• Henry Draper No : for example HD 48915
• Hipparcos No : for example HIP 32349
• Tycho Designation : for example TYC 5949-2777-1
