RCW 42 is a large HII region in the constellation of Vela, it is also known as Gum 26. It lies at the western edge of the immense galactic chimney GSH 277+00+36. There is minimal information concerning RCW 42 given that itis probably one of the greatest regions of star formation in the Milky Way. The RCW Catalogue (from Rodgers, Campbell & Whiteoak) is an astronomical catalogue of Hα-emission regions in the southern Milky Way, described in (Rodgers et al. 1960). It contains 182 objects, including many of the earlier Gum catalogue (84 items) objects. The RCW catalogue was compiled by Alexander William Rodgers, Colin T. Campbell and John Bartlett Whiteoak. They catalogued southern nebulae while working under Bart Bok at the Mount Stromlo Observatory in Australia in the 1960s.
