Caldwell

The Caldwell catalogue, created in 1995 by Sir Patrick Caldwell-Moore, includes 109 galaxies, clusters, and nebulae meant for observation and imaging. Although the Messier catalogue is more well-known, the Caldwell list offers valuable targets. The objects are visible in both hemispheres and are ranked by declination. For me, Caldwell objects numbered 60 and higher cannot be photographed from the backyard.
