| Abstract: |
To point a telescope to a sky region devoid of bright stars is a typical
procedure when obtaining calibration images for astronomical observations. To
date, no systematic catalogue is available providing the location in the sky of
blank fields for varying limiting magnitudes. In this work we describe a method
that helps to determine the availability of blank fields in any region of the
celestial sphere, based on the use of the Delaunay triangulation. In addition,
we present TESELA, a Virtual Observatory tool which provides a simple interface
that allows the user to retrieve the list of blank fields available near a
given position in the sky. |
