To import an existing data file, enter its filename here. You will then describe the contents of the file below. You can leave the filename blank to construct a catalog file with a valid header, but no data.

Contents of the imported data file

When you select a data file in the above line, its contents are displayed here.

mm

This button will compute the field-of-view (FOV) angle for a specific eyepiece/telescope combination. You must first specify the focal lengths of the telescope and eyepiece, and the FOV angle of the eyepiece in the above entry fields. The computed FOV angle (in arcminutes) will be displayed in the "Field of view" edit box.

This button will compute the field-of-view (FOV) angle for a specific camera/telescope combination. You must first specify the focal length of the telescope and the size of the CCD chip or film negative. The computed FOV angle (in arcminutes) will be displayed in the "Field of view" edit box.

Enter the physical size of the CCD chip or film negative. This is one of the data fields required for defining a field-of-view (FOV) symbol which matches the field-of-view of a camera mounted on a telescope.

cm

This button will compute the Half Power Beam Width (HPBW) angle for a specific radiotelescope and observing wavelength combination, assuming no multibeam receiver is available at the telescope. You must first specify the diameter of the radiotelescope and the observing wavelength. The computed HPBW angle (in arcminutes) will be displayed in the "Field of view" edit box.

Desired field-of-view size, in arcminutes

Enter the desired angular size for the field-of-view (FOV) symbol. You can either enter a value directly, or use the "Eyepiece" or "Camera" Tabs to compute an angular size for specific eyepieces or cameras.

Stars fainter than this will not be drawn while the map is moving.

If checked, then objects in the IC catalog will be hidden when the map is in motion.

If checked, then the Milky Way contour will be hidden when the map is in motion.

If checked, then all solar system bodies will be hidden when the map is in motion.

If checked, then objects in the Messier catalog will be hidden when the map is in motion.

If checked, then the coordinate grid will be hidden when the map is in motion.

If checked, then objects in the NGC catalog will be hidden when the map is in motion.

If checked, then constellation lines will be hidden when the map is in motion.

If checked, then constellation names will be hidden when the map is in motion.

If checked, a contour representing the Milky Way will be drawn on the sky map

If checked, the Milky Way contour will be shown filled. Otherwise, only the outline will be drawn.

If checked, a grid of lines will be drawn every 2 hours in Right Ascension and every 20 degrees in Declination.

If checked, the celestial equator will be drawn in the sky map.

If checked, the ecliptic will be drawn on the sky map. The ecliptic is a great circle on the sky that the Sun appears to follow over the course of one year. All other solar system bodies roughly follow the ecliptic as well.

If checked, a line representing the local horizon will be drawn on the map.

If checked, the area below the horizon will be filled in, to simulate the ground beneath you. Note that the ground is never drawn when using the Equatorial coordinate system.

Attach Name labels to the major solar system bodies?

If checked, name labels will be attached to the planets, the Sun and the Moon

Press this to select all planets, the Sun and the Moon to be drawn in the map
