The Messier Catalog is one of the oldest and most useful resources in astronomy. Compiled by Charles Messier in the 18th century and updated throughout the years, this catalog has served as the foundation for countless amateur astronomers. The Messier Catalog provides a convenient and historic list of deep sky objects. Although the Messier list was compiled for eyepiece viewing, these objects also make great imaging targets. This 112 page book was written to assist astrophotographers who wish to capture these amazing Messier objects from their backyards. The book also contains highlights of the Caldwell catalog, for a total of 150 objects to pursue throughout the year. Inside you will find a high resolution image and a description of each object, along with technical data to help you to understand their characteristics and to assist you in finding them in your sky. The data provided for each of the 150 objects includes imaging rating, transit date, distance, actual & apparent sizes, star color index, magnitude, galaxy inclination & brightness, and cluster star mass. This book is the 7th in the Imm Astrophotography Series. This series of books is written to help the astrophotographer who struggles to find suitable and interesting targets in the night sky. Each book shows, describes and rates objects ranging from nebulae to galaxies to star clusters. These books allow the astrophotographer to best use every clear sky minute on each night of the year.
