Astronomy constellations

Orion Constellation This is a mosaic picture of 18 (6x3) frames. Additional four frames are added around the Barnard Loop region to increase S/N. Vignetting of the telescope is corrected by flat fielding, using proprietary software written in IDL. Distortion correction and initial colour match is done in Registar, with final colour correction and mosaic processed using Photoshop.

Celsius was a professor of astronomy al Uppsala University. He is noted for trying to determine the magnitude of the stars in (he constellation Aries. He published 316 of his observations on the aurora borealis. 

Beyond the outermost planet, the crystal sphere that carries the fixed stars, was located, showing the placement of the twelve constellations of the zodiac. For the first time it became possible to draw up accurate maps of the sky to coincide with important moments or events, past, present or future, in the life of individuals or nations. This is the basis of astrology, in which Ptolemy was as expert as in astronomy. For the purpose of our discussion this issue is of no importance, but for millions, over millenia, it provided a method to avoid disaster, make informed decisions and foretell the future.
