NOVA 120 Pointing model user manual

Plate solving, that is having each pixels X and Y image’s coordinates to be translated into RA and DEC coordinates, is a
fundamental step and must work.
PRISM embeds this step automatically by matching the star of the image with a catalog. Nevertheless, this feature shall
be checked and shall work;
otherwise no pointing model can be build.
Slew to a star that can be identified with the sky map, which is not too bright, and be sure this star is located into the
camera’s field of view.
The next image shows the star and the sky map that matches to it.
Then re-center the star so that it is located at the image’s center.
