18" (7/11/05 - Magellan Observatory, Australia): very bright, fairly large, very elongated 3:1 SW-NE. Very well concentrated with an intense 20" core. The outer extent increases with averted vision and fades at the tips with overall dimensions of ~2.0'x0.7'. At the NE edge of the core is a very small, bright knot appearing similar to an offset nucleus of a galaxy, particularly using direct vision. This small starburst galaxy is classified as a "Blue Dwarf" and harbors Super Star Clusters (SSC) near its nucleus. NGC 5253 is likely part of the M83/Cen A group.
13.1" (5/26/84): bright, elongated, very bright core.
8" (5/21/82): bright, elongated SW-NE, bright core.
