Solun'-u application should operate on most devices supporting MIDP 1.0. It works best with a colour screen but black and white devices are supported. It has been tested on the Nokia 7210, Nokia 7650 and Siemens SL45i.

Features include:

Multiple views
. Simple sky charts: horizon, zenith and ecliptic views.
. Interactive 3D orrery display.
. World map display.
. Moon phase display, including eclipse simulation.
. Galilean moons of Jupiter.
. Saturn rings display.
. Various charts showing movement over time.

Information panels
. Information panels for sun, moon and planets.
. Customisable database of comets and asteroids.
. More accurate than previous versions of Solun.
. Includes eclipse prediction for observer's location.

Features include:
. All stars brighter than magnitude 4.0 clearly visible in a graphic rendering of the sky. Dimmer stars needed to complete the constellation figures are also included, with an accurate reproduction of each star's color.
. Over 100 common star names, including all the standard navigational stars.
. Accurate calculations of the positions of the planets, Sun and the Moon for your location.
. An accurate representation of the current phase of the Moon.
. An intuitive way to determine what is in your sky currently, regardless of the size of your cell phone's screen.
. Wireless network access not required! If you're lucky enough to find yourself at a very remote dark sky site, all of picoSky features will still work. picoSky has completely self contained databases and harnesses the computational power of your cell phone to create a graphical representation of the sky.
. Geometric figures and names for all 88 constellations.
. Over 250 of the brightest and most popular deep sky objects, with each type (globular cluster, open cluster, galaxy, nebula, planetary nebula, and asterism) easily identifiable. If available its common name is also included.
. Search for and find any star, constellation or deep sky object in picoSky's databases and obtain detailed information for that object. A quickly accessible menu also gives you detailed information about the Sun, Moon and each planet. For example: Distance from the Earth and Sun for the planets, Moon, and Sun; Rise, Transit, and Set times ; Right Ascension and Declination coordinates ; Altitude and Azimuth coordinates ; The ability to view the object if above the horizon.
. View what will be or what was in the sky for any given date and time within thirty years from the present.
. Access to a database containing latitudinal and longitudinal coordinates for every telephone area code in the U.S. for simple location selection. Or for more precision, enter your exact location in degrees, minutes and seconds of latitude and longitude.

• The scopes aperture in mm
• The scopes focal length in mm
• The scopes max power
• The scopes min power
• The scopes resolving power
• The scopes exit pupil for an eyepiece
• The scopes power for an eyepiece
• The scopes actual field of view for an eyepiece
• As an added bonus you can compare the actual FOV of your selection to a bitmap of Andromeda (the image pans).

A MIDP1.0/2.0 midlet for most Java-enabled mobile phones (cell phones). Simulates whole sky at any point on earth with constellations, stars up to 6 mag, solar systems and some other celestial objects. It may be a useful tool when you are bathed under star lights with your cell phone in the pocket. This also gives you a serious and detailed guide of current sky above your head at your location.

Features:

Both Horizontal and Equatorial Coordinate Display of whole sky. 88 constellation names, 83 constellation stick figures, 10 messiers and stars up to mag 6.0 (5080 stars, and 50 common star names).
• All 8 planets plus Sun and Moon is calculated, information is displayed respectively on a seperate screen.
• Location and Date/Time can be set at startup.
• Applicable for any location on earth given a specific time.
• Auto update of celestial object positions.
• Sophisticated display control over all information on screen.
• Support English and Chinese display of celestial object name.
• Tiny 150KB compressed jar file. (All 6 mag stars insides, for version 0.08)
