Star Chart (Figure 3) shows stars and objects from selected layers and ALL objects from the current observation list. You could demonstrate either all objects from the current observation list, or non-marked ones only.

Besides stars the chart depicts bright star and object labels, bright planets, alt-azimuthal or equatorial grid line, horizon line, user horizon line, constellations, selected eyepieces field of view (red dotted circles), Telrad rings, selected object marker, downloaded DSS images and their contours6.

At the bottom there is a control and information zone. It shows the name of the currently selected object along with its magnitude, azimuth and altitude coordinates as well as chart time and ra/dec coordinates of the chart center. Press at the buttons in the zone center to change field of view (90, 60, 45, 30, 20, 10, 5, 2, 1, 30', 15', 7.2', 3.6' degrees). Press on the name of currently selected object to get object information. Press on the chart time to set a new date/time, and/or turn on/off real time mode.

By default double star info (component and separation) is shown as double star label. This could be turned off in Settings, Double Star Info.

To distinguish observation list objects from layer objects you could (a) show labels for the first, and not for the second, (b) dim object from layers and (c) put a colon (:) after the name of selected object as shown in control and information zone.

Layer objects could be limited either by their magnitude or visibility in selected equipment in the current sky conditions. With the latter option you could see objects visible in your telescope just as you swipe star chart!

You could measure angular distance between any star / objects. Just tap on the first star / object, and then on the second star / object. The measured distance is shown in the upper left.

Main features

Depending on the current field of view (FOV) the program shows:

The chart also depicts icons of bright solar system objects: Sun, Moon, Venus, Mars, Jupiter, Saturn.
