- Description: Running from upper right to lower left is a chain, or cascade of 20
stars. These have been named Kemble's Cascade after the late Fr. L. Kemble (1922-1999), who brought
this asterism to the attention of Walter Scott Houston of Sky and Telescope magazine. Houston was
so impressed that he wrote an article on the asterism that appeared in his Deep Sky Wonders column
in the astronomy magazine Sky & Telescope in 1980, in which he named it Kemble's Cascade. The cascade
ends with an open cluster, NGC1502. (aka Herschel H VII-47) This cluster is a visual treat, consisting
of many pairs of double stars.
