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 >67 cannot be photographed from the backyard.
