Constellations DS is a planetarium for Nintendo DS. It includes the 88 modern constellations, with at least the stars up to magnitude 5, as well as the 110 Messier objects. It offers the possibility to visualize the night sky and navigate/zoom within it, to select a star to obtain its name, coordinates, and magnitude, to display the image of a Messier object, and to search for a specific constellation or star.


Constellations is a planetarium for DS Nintendo DS. The objective is to enable learning and pattern recognition and the names of constellations. Provide a source of scoring simple, fast and portable for comments amateurs. It includes the 88 modern constellations, with each of them stars up to at least magnitude 5, and the 110 Messier objects.
It was a contest entry to the Dev-fr Coding Compo 2007 (Applications, 2nd place).
 
It was presented in the [http://www.playeradvance.org/forum/showthread.php?t=6667 Dev-fr Coding Compo 2007] with the theme Evolution, sponsored by DS-X, ranked 2nd in the App section.

'''Important note about the positions:'''
===About the positions===
* The positions are purely illustrative and should not be used as source for telescopes pointing accuracy. They are nevertheless sufficient for most amateur and instruments for observing with the naked eye.
The positions are purely illustrative and should not be used as source for telescopes pointing accuracy. They are nevertheless sufficient for most amateur and instruments for observing with the naked eye.
* Because of the limited technical capabilities of the Nintendo DS for calculations trigonometric precision of the position is the order of one minute of arc.


'''Important note about the magnitudes:'''
Due to the limited trigonometric calculation capabilities of the Nintendo DS, the precision of the position is approximately one arcminute.
* The magnitude of the objects are given for information. Their accuracy is about hundredth of magnitude.
* The magnitude of 5.00 is shown a magnitude limit intrinsic to the application; So if a star is displayed with a magnitude of 5.00, one must understand magnitude ≥ 5. This does not apply to the Messier objects.
* All-Star Constellations DS should be visible to the naked eye, a beautiful night without excessive light pollution.


'''Screen sky:'''
===About the magnitudes===
* Sky on the screen are displayed the stars and Messier objects, and the constellation lines and a grid if enabled in options.
* Each star is represented by a filled circle whose size depends on the magnitude of the star (the star is more brilliant, more the circle is large).
* Messier objects are represented by circles. No formalism for existing lines of the constellations, they are given for information to better recognize and memorize the constellations by their form. The grid step is 1 hour in right ascension and declination of 15 degrees.


==Control==
The magnitudes of objects are provided for reference. Their precision is approximately to the hundredth magnitude.
 
The displayed magnitude of 5.00 is an intrinsic limit magnitude of the application; therefore, if a star is displayed with a magnitude of 5.00, it should be understood as magnitude ≥ 5. This does not apply to Messier objects. All stars in Constellations DS should be visible to the naked eye on a clear night without excessive light pollution.
 
===Sky vault screen===
 
On the sky vault screen, stars and Messier objects are displayed, along with constellation lines and a grid if they are activated in the options.
 
Each star is represented by a solid circle, the size of which depends on the star's magnitude (the brighter the star, the larger the circle).
 
Messier objects are represented by empty circles. There is no formalism for constellation lines; they are provided for reference to aid in recognizing and memorizing constellations by their shapes. The grid spacing is 1 hour in right ascension and 15 degrees in declination.

Constellations DS is a planetarium for Nintendo DS. It includes the 88 modern constellations, with at least the stars up to magnitude 5, as well as the 110 Messier objects. It offers the possibility to visualize the night sky and navigate/zoom within it, to select a star to obtain its name, coordinates, and magnitude, to display the image of a Messier object, and to search for a specific constellation or star.

It was a contest entry to the Dev-fr Coding Compo 2007 (Applications, 2nd place).

Features

  • View the sky and move around/zoom.
  • Select one star to get his name, address and its magnitude.
  • Display the image of a Messier object, and find a constellation or a specific star.

User Guide

Main Mode

In the main mode, the information screen is located on the upper screen of the DS, while the screen representing the night sky is on the lower screen. This mode allows you to navigate, zoom, and select a star or Messier object.

  • In each frame, from top to bottom:
  • Name of the constellation/Messier object number.
  • Name of the star/Messier object name.
  • Position (right ascension in hours:minute, declination in degrees:minute).
  • Apparent magnitude in the visible domain.
  • Image of the selected Messier object.

In the bar at the bottom of the screen from left to right:

  • Zoom Level.
  • Right ascension of the center of the screen in hours: minutes.
  • Declination of the center of the screen in degrees: minutes.
  • Size of field of view in degrees x depth (width x height).

About the positions

The positions are purely illustrative and should not be used as source for telescopes pointing accuracy. They are nevertheless sufficient for most amateur and instruments for observing with the naked eye.

Due to the limited trigonometric calculation capabilities of the Nintendo DS, the precision of the position is approximately one arcminute.

About the magnitudes

The magnitudes of objects are provided for reference. Their precision is approximately to the hundredth magnitude.

The displayed magnitude of 5.00 is an intrinsic limit magnitude of the application; therefore, if a star is displayed with a magnitude of 5.00, it should be understood as magnitude ≥ 5. This does not apply to Messier objects. All stars in Constellations DS should be visible to the naked eye on a clear night without excessive light pollution.

Sky vault screen

On the sky vault screen, stars and Messier objects are displayed, along with constellation lines and a grid if they are activated in the options.

Each star is represented by a solid circle, the size of which depends on the star's magnitude (the brighter the star, the larger the circle).

Messier objects are represented by empty circles. There is no formalism for constellation lines; they are provided for reference to aid in recognizing and memorizing constellations by their shapes. The grid spacing is 1 hour in right ascension and 15 degrees in declination.

Controls

Stylus - Select, Control speed

Up/X - Zoom in
