The Magellanic Clouds are located in an area of sky fairly devoid of bright stars, although these two objects more than make up for this deficit. A pair of 7ϫ50 binoculars is all you need to scan the Clouds for star clusters and nebulae. In the LMC, the most striking feature is the Tarantula Nebula, designated NGC 2070,* clearly visible to the naked eye at the southeast end of the Cloud.

Today, the point in the sky from which the meteors appear to emanate is located in Boötes.
