A Map of the Constellations?

An excerpt from the blogspot Infallible Catholic: " On December 22, 1981, at the Observatory Laplace Mexico City, Father Mario Rojas and Dr. Juan Hernández Illescas, a medical doctor and amateur astronomer, performed an astronomical study of the Image and analyzed the stellar arrangement that appear in the Mantle of Our Lady. They surprisingly discovered that the stars stunningly and accurately map out the various constellations of the Mexican sky. Even more remarkable is the "star map" on the mantle is in the reverse (the cardinal axis rotated 90 degrees counterclockwise): providing a view of the constellations from beyond them, as would be seen looking through them towards the earth. The constellations are consistent with what astronomers believe was in the sky above Mexico City on the day the apparition occurred  - in the winter-morning solstice of December 12, 1531, Saturday, at 10:26AM.
Our Lady's cloak has 46 stars: 22 on her right side, and 24 on her left side. These 46 stars are the most brilliant stars that surround the horizon of the Mexican Valley which have been identified. The main constellations of the Northern sky can be seen on the right of the mantle. On the left, the Southern ones which can be seen from the Tepeyac in winter at dawn. The East is situated in the upper part and the West in the lower part. The Mantle is opened and there are other groups of stars which are not marked in the Image, but they are present in the sky. The Boreal Crown is located above the Virgin's head; Virgo is on her chest, in the region of her hands. Leo on Her womb, precisely above the sign of Nahui Ollin, with his main star Regulo, the small king. Gemini, the twins, is found in the region of the knees and Orion is located where the Angel is."
