QWERTY Keyboards

QWERTY devices such as the Motorola Q shown below can use the following keyboard shortcuts:

image

image

Main Menu

Activate the main menu by pressing the right soft button.

image

Location

Controls the zenith point used when drawing the star chart. You can either select a city from the list or enter the latitude and longitude manually. The first entry in the Cities list is "Custom" and is automatically selected if the latitude or longitude fields are manually changed.

Areas of the earth currently experiencing night are shown in darker shades.

image

Time

Controls the time at which the star chart is valid above the selected Location.

Realtime. If checked, continuously update the star chart with the current Smartphone time. If unchecked, you may specify a particular time using the date and time fields.

UTC. If checked, the time selected is in Coordinated Universal Time (UTC). Otherwise, time is entered as local time using the offset from UTC established by the following fields.

Time Zone. Time Zone specifies the how local time differs from UTC, expressed in hours. Each time zone covers 15° of longitude. Locations west of Greenwich have negative offsets, while locations east of Greenwich have positive offsets. The time zone may be set using three different methods:

System - Uses the time zone established by the device clock. This is controlled by "Start.Settings.Date and Time".

Longitude - Uses the current geographical location (specified in the Location page) to calculate Zone Time. While correct for many locations, this method does not take into account the effect of political boundaries.

Custom - Enables a list box which you can use to set the Time Zone.

DST. If checked, indicates Daylight Savings Time is in effect.

View, 2D - Star Chart

Displays a planisphere from any position on earth at any given time.

Press the OK/Action key to switch to full screen mode and display a list of keyboard shortcuts. Press OK/Action again to hide the shortcut menu. Subsequent OK/Action key presses toggle between "scrolling" mode and "selecting" mode.

The "." (period) key rapidly toggles between 2D and 3D modes.

Displays a view of the solar system from locations other than earth. Zoom moves the viewing location toward and away from the sun. Scrolling rotates the viewing location.

Press the OK/Action key to switch to full screen mode and display a list of keyboard shortcuts. Press OK/Action again to hide the shortcut menu. "Selection" mode is disabled in 3D view..

The "." (period) key rapidly toggles between 2D and 3D modes.

Illumination percentage for the selected date is shown at the bottom of the dialog.

Use the left and right arrows to increment and decrement by one day.

Animation

Let's you step forward and backward in time.

First select the unit of time by which you wish to increment and decrement. Then select "Step +" or "Step -" to move forward or backward by that unit.

This is especially effective in 3D Orrery mode to note the relative planetary positions over time.

Star Magnitudes

Controls the minimum brightness of stars displayed on the chart.

Auto reduces screen clutter by automatically adjusting the number of stars displayed appropriate to the zoom setting. Otherwise, the number of stars displayed depends on the magnitude selected:

Magnitude Number of Stars
0 4
1 15
2 48
3 170
4 513
5 1604
6 5023
7 9046
8 9096

Horizon - Rotate

Positions any of the 8 compass points at the top of the chart. Also allows reversal of east and west.

Home - Zenith Remove all scrolling effects so that the stars directly overhead are positioned at the center of the display. Zoom factor is set to 1.5. Note that a green X marks the zenith point directly overhead.

Flip East and West. If checked, the star chart is flipped along the North - South axis. Leave this option unchecked if viewing the computer display in-line with the sky. For example, leave this option unchecked if lying on your back with the screen overhead. If checked, the display is mirrored along the North - South axis, switching the positions of East and West.

Find - Info

Used to select a star, planet, sun, moon, constellation, or Messier and Caldwell object. The selected object will be centered on the star chart if currently visible and Done is chosen. An image of the object is displayed if available. Choose "Info" to show a text description of the object.

Messier and Caldwell images can be downloaded automatically if you have an internet connection to your Smartphone (either phone network or ActiveSync). If not, you can download the images files manually from this page. Select the ARM processor.

Checking the "SDSS" displays images from the Sloan Digital Sky Survey if you have an internet connection. You can zoom in and out using the "+" and "-" buttons. Note that SDSS does not cover the entire sky: most objects in the range M80 to M100 are within the survey.

image The "Info" menu choice switches to a detailed listing of measured and calculated values pertaining to the body.
