The easiest way to personalize your own celestial map is to print it through a company that already has a system set up for finding the right positioning of the night sky on that date. There are a handful of websites that do this now, and it only takes a few minutes to input your information and get a precise image. Though sites are normally very accurate, you can double-check the map before submitting it for printing through several scientific websites that record and keep track of the night sky.
