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.

===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.


'''Main Mode'''

The display information is located on the top screen of the DS, and screen representing the sky on the lower screen.

'''Information Display'''
 
The information screen provides information about viewing the sky and the star / Messier object selected.

'''Important note 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
Due to the limited trigonometric calculation capabilities of the Nintendo DS, the precision of the position is approximately one arcminute.
trigonometric precision of the position is the order of one minute of arc.
 
 
'''Important note about the magnitudes:'''
 
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'''
 
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.

handers than left-handed. Follows a list of possible actions in the main mode.


===Commandes===
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.
'''Displacement:'''


Moving on the screen sky is full pen, by acceleration, ie relatively initially received at the location. It is therefore unnecessary to take up the pen until the move is complete.
===Sky vault screen===
The speed depends on the zoom level and the deviation from the affected area initially.


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.


'''Selection:'''
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).


Just touch a star or a Messier object to select it.
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.
The star or object, then signaled by red vertical markers, then focuses on the screen celestial vault, and its data are displayed on the top screen.
Note: sometimes the selection can be difficult ... In this case, a slight effecutez

'''Zoom:'''
Up/X - Zoom in  
You can zoom in with high / X in and out with low / B. If the mode "rapid movement" is not enabled, a long press allows (un) zoom in continuous.
The zoom can take values ​​ranging from 256 to 3584, the latter corresponding to a maximum zoom, in increments of 256. The present value of the zoom is displayed at the bottom left of the screen information.
Note: depending on the values ​​of the zoom, and for the sake of clarity, not all stars are not displayed. To zoom of 256/512, only stars brighter than 3rd/4th magnitude are displayed. For all other values​​, all the stars appear on the screen sky.


Down/B - Zoom out


'''A review:'''
Left/Right/Y/A - Quickly move from one constellation to another, or Messier object to another
Constellations DS offers the ability to quickly move from one constellation to another, or Messier object to another, with left / right and Y / A. The order for the constellations is alphabetic, numeric Messier objects.
The choice between constellations and Messier objects depends on the final selection, but can be switched with the select button.


Select - Switch constellations and Messier objects


===Mode Menu===
R/L - Access mode menu (change options, look for constellations and stars, and enlighten you in the dark night)


In Menu mode, the screens are reversed in order to use the stylus for different selections. The Movement and review are therefore more possible, but the zoom remains operational.

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.
