     You can tweak various settings to make the orientation of the sky map match the view through your optical instrument, provided (as of this version) the instrument does not mirror the field-of-view (as is done by prisms used with SCTs and refractors).

-    First, pick the coordinate system that matches your mount. For an equatorially mounted instrument, switch to the Equatorial Coordinate mode in the <guimenu>View</guimenu> menu. The option to toggle the coordinate system should read <guilabel>Switch to Horizonal View (Horizontal Coordinates)</guilabel> when the current mode is Equatorial Coordinates. For an altazimuth-mounted instrument or naked-eye viewing, switch to Horizontal Coordinates, so that the option in the <guimenu>View</guimenu> menu reads <guilabel>Switch to Star Globe View (Equatorial Coordinates)</guilabel>. This sets the base coordinate system used to render the sky map, and also sets the reference for the orientation of the skymap: zenith or north.

     To rotate the sky map freely, you can hold down the Shift key and drag the mouse on the sky map. A temporary overlay will appear showing the direction of north and zenith at the point, and displaying the angle they make with the vertical in a counterclockwise sense. The orientations of zenith and north will update as you rotate the sky map. Letting go of Shift or the mouse button will stop the rotation operation. As you pan the sky map or focus it on different objects, the rotation you set is retained as an offset from the reference direction. The reference direction is north when using Equatorial Coordinates and zenith when using Horizontal Coordinates. As a reminder, the reference direction is solid and brighter in the temporary overlay. For the two common orientations of erect and inverted, the rotation can be set / reset using the <menuchoice><guimenu>View</guimenu><guisubmenu>Skymap Orientation</guisubmenu></menuchoice> submenu. Select "North Down" or "Zenith Down" as is applicable to set an orientation of 180 degrees.
