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 ...
