Grasslands : Table of Southern Caldwell Objects

Sir Patrick Alfred Caldwell-Moore, one of Britain's most respected astronomers and one of the world's most renowned astronomical writers, compiled a list of 109 deep-sky objects for those who wish to go beyond the Messier Objects. This list was first published in the December 1995 issue of Sky & Telescope, and it has been supported and popularized by Sky & Telescope.

These objects are both challenging and spectacular. They cover a wide range of sizes and magnitudes. Some are large, bright, and well known. Others are faint, small, and very difficult. It is impossible to image them with the same instrument and the same imaging parameters. Unlike the Messier Objects, they can not be observed only from the Northern Hemisphere. At least 30 of the objects require Southern skies for proper observation. Unlike most other observing lists, the Caldwell Objects are presented in order of declination from North to South.

To learn more about the Caldwell Objects, the following books are highly recommended:

1. O'Meara SJ. The Caldwell Objects. Sky Publishing Corporation, 2002.

2. Ratledge D. Observing the Caldwell Objects. Springer, 2000.

The present color images of the Southern Caldwell Objects were taken by Chris Picking of New Zealand. He has graciously consented for them to be displayed here.

Please check out his Starry Night Skies Photography website.

Many of the Caldwell Objects can be equally observed from either hemisphere. The Southern Caldwell Objects depicted herein are those that can not be seen at all or very poorly from the Southern part of the United States.
