In order to calculate the position of a star in the nightly sky, we need to agree to an epoch and use a catalog that contains the position of the stars at the chosen epoch. For my project I will use epoch J2000 and the Bright Star Catalog. This catalog contains 9110 stars with magnitude greater than +6.5, meaniing that are visible to the naked eye. This number is too large to our application, since the laser just gives us a coarse position in the sky. The first tests will be made with a list  with a number of stars one or two orders of magnitude lower.
