ABOUT THIS IMAGE:
The RCW Catalogue (Rodgers, Campbell, Whiteoak) is an Astronomical catalogue of Hα-emission regions in the southern Milky Way, described in (Rodgers et al. 1960). It has 180 objects and includes many of the earlier Gum Catalog (84 items) objects, and the later Caldwell catalogue included some RCW.
Catalogue was compiled by Alexander William Rodgers, Colin T. Campbell
and John Bartlett Whiteoak, who led by Bart Bok, catalogued southern nebulae
while working at the Mount Stromlo Observatory in Australia in the 1960s.
