Sky popup

Tapping on the Sky near an object will bring up a popup menu with basic information about that object, or just location if not near any object. The popup also offers these controls:

• More info... displays a separate dialog with additional information which may include position reported in several coordinate systems; when and where it will rise, transit and set today; the page on which it occurs in several popular atlases; and additional information relevant to the type of object and the current Options. Tapping more than several pixels from any object reduces the information to the basics about that spot.
• Center shifts the RA and Dec so the tapped spot is centered.
• Zoom in 5x is like Center but also reduces the field size by a factor of 5.
• Place Eyepiece adds a new eyepiece centered at the tap position. The specifications are those currently set in the Eyepiece control.
• Add to Favorites adds the object, or tapped location, to the list of Favorites.
• Track locks the display position to follow the given object. This makes it easy to watch an object move against the background of stars by advancing time. A T is drawn in the upper right corner to indicate when Tracking is on. Tracking remains in effect until the Sky position is explicitly changed with the sliders or popup commands, or implicitly by invoking a Favorite, zooming to Search result or other means.
