CATALOGO MESSIER PDF

His notoriety is due to the fact that the catalog of Messier was the first catalogue that listed and numbered the main objects of the sky, different from the stars. In the literature, there is ample and rich documentation, both on the bibliography of Charles Messier and is on his Catalog of Nebulae and Star Clusters. References for specific analysis are listed in the note bottom of this page. In this context I would like instead to present a gallery of photographs, already showed in this website, particularly in the Tabulae Coeli section.

Look at Galaxies During the years from to Charles Messier , a French astronomer - , compiled a list of approximately diffuse objects that were difficult to distinguish from comets through the telescopes of the day.

Fortunately for us, the Messier Catalog became well known for a much higher purpose, as a collection of the most beautiful objects in the sky including nebulae , star clusters , and galaxies. It was one of the first major milestones in the history of the discovery of Deep Sky objects , as it was the first more comprehensive and more reliable list: Only four or five objects were initially missing because of data reduction errors, which could be figured out later though.

The purpose of these web pages is to provide a complete guide to the objects recognized as the standard Messier catalog. More importantly, we would like to generate interest in astronomy , the night sky and the universe beyond us, and to encourage a sense of wonder and exploration. We also hope that these pages may be useful as a reference for amateur astronomers.

For each object, an image is presented together with a short description; click on the image to get a larger-format version. In addition to the images, we have also included some data on these objects such as celestial position right ascension in hours and minutes [h:m], declination in degrees and minutes [deg:m], both for the epoch J In order to enjoy the full comfort of this HTML level, we recommend to use the most recent release of Netscape 2. Moreover, we try to keep the pages appealing or at least readable under less advanced browsers such as Mosaic or Lynx; please complain if your browser has certain problems!

We thank all who have expressed interest in these pages, and have sent us e-mail with suggestions and corrections. The contributions of others have significantly influenced what the pages are now. We hope to further approach the state of a top-of-the line resource with in-depth information including object descriptions, "star-hop" techniques to easily locate the objects with small telescopes, and more.
