Um bom começo é instalar o Skychart, existe a versão para Linux e Windows. Super fácil de instalar. Astronomia para iniciantes. SkyChart is a software to draw chart of the night sky for the amateur astronomer from a bunch of stars and nebulae catalogs. See main web page for full download Create a custom naked-eye map of the whole sky for any place on Earth, at any time of day or night, on any date from 1600 to 2400. Our Interactive Sky Chart works in most Java-enabled Web browsers.

Add Tirion constellation figures created by James Trogolo
Catalog and data:
New default star catalog based on Extended Hipparcos to replace the BSC and Sky2000.

New online Internet resources:
Add any catalog from Vizier, allow for full or partial download.
Search Simbad, NED, Vizier.
Link object detail to Simbad, NED, HyperLeda.
Add Mercator projection.
Cartesian and Mercator projection are rotated to the screen center for full sky coverage.
Change the default projection to Tangent for FOV up to 90 deg. and Mercator for wider fields.
Limit the use of Arc projection to 250 deg. FOV.
Limit the vision of objects below the horizon to 180 deg. FOV.
Improved precision of the apparent coordinates (many thanks to P. Wallace for its help):
Take account of the radial velocity to compute the proper motions.
Light deflection by the Sun.
Extended time validity for nutation and aberration if using DE422.
Compute the precession using “New precession expressions, valid for long time intervals, J. Vondrak, 2011”
Compute DeltaT values from “Five Millennium Canon of Solar Eclipses, Espenak & Meeus, 2006”
Extend the allowed date to +/- 200’000 years
Make a portable installation of Skychart
A portable install mean you install Skychart on a removable media (USB stick) and you can plug it to any PC to run the application without any further configuration.
This require a version more recent than 3.7-2196 to properly handle any change in the media mount point on different computer.
The example is given here for Windows but you can do almost the same on Linux, in this case use the tar installer for an easy setup.
The commands suppose your removable media is mounted on E: change accordingly if it use another letter.
This description use mostly a command line window for the clarity of the explanation but you can also use the equivalent graphical tool.
To open a command line window use the Start menu → Accessories → Command Prompt
1) Create a new folder on your removable media:
2) Copy the program code:
xcopy /S “C:\Program Files\Ciel*” Ciel\
If you not want to install the Skychart software on your computer, see the additional steps below
3) Create a folder for the program configuration:
4) Create a startup script:
Type the following and save the file:
start %basedir%\Ciel\skychart.exe –config=”%basedir%\userdata\skychart.ini” –userdir=”%basedir%\userdata”
Now you can plug this USB stick on any (Windows) computer and run the program with a double click on skychart.cmd.
