Herschel 400 Catalogue

Jump to: navigation, search

The Herschel 400 catalogue is a subset of William Herschel's original Catalogue of Nebulae and Clusters of Stars, selected by Brenda F. Guzman (Branchett), Lydel Guzman, Paul Jones, James Morrison, Peggy Taylor and Sara Saey of the Ancient City Astronomy Club in St. Augustine, Florida, USA c. 1980. They decided to generate the list after reading a letter[1] published in Sky & Telescope by James Mullaney of Pittsburgh, Pennsylvania, USA.[2]

In this letter Mr. Mullaney suggested that William Herschel's original catalogue of 2,500 objects would be an excellent basis for deep sky object selection for amateur astronomers looking for a challenge after completing the Messier Catalogue.

The Herschel 400 is a subset of John Herschel's General Catalogue of Nebulae and Clusters published in 1864 of 5,000 objects, and hence also of the New General Catalogue.

The catalogue forms the basis of the Astronomical League's Herschel 400 club.

Vital statistics[edit]

Distribution of Herschel 400 objects[edit]

Distribution of Herschel 400 objects
Red = Galaxies, Green = Nebulae, Yellow = Star Clusters

Herschel 400 objects which are also Messier objects[edit]

The Herschel 400 contains a few objects which are currently considered to be part of the Messier catalogue. For example Messier never published M104 to M110[3] in his lifetime they were added in the 20th century, an explanation as to why this is appears below:

Herschel 400 objects which are also Caldwell objects[edit]

The Herschel 400 catalogue pre dates the Caldwell catalogue. The Caldwell catalogue contains the following objects which are members of the Herschel 400:[4]
