Starry Night Pro FAQ

Back to Main FAQ

The star data for the nearest million or so stars comes from the Hipparcos/Tycho catalogue, which is the result of a recent mission by the European Space Agency. Find out more about this catalog at the Hipparcos Project home page. The star data for dimmer stars comes from the Hubble Guide Star Catalog. Stars from this catalog are distinguished by the "GSC" at the beginning of their names.

Yes, if you have sufficient space (the files are about 400MB in total. There is a folder named "Hubble" on the CD. Move each file in this folder into the "Starry Night Pro\Starry Night Pro Data" folder on your hard drive. You cannot simply move the "Hubble" folder and make it a subfolder of "Starry Night Pro Data", but must move each file individually. After you do this, you will not need the CD at all when you run Starry Night, unless you want to look at one of the pre-made files in the "Eclipses" folder.

Unfortunately, no. Starry Night will only display the Hipparcos or Tycho number.

No, this is a limitation of our star catalog. Starry Night has distances to about 100 000 stars from the Hipparcos Catalog. Most of the stars in this catalog are within a few hundred light years of the sun, so as you zoom out farther than this, they appear to cluster around the sun.

No. A future version of Starry Night may add this feature.
