Alex Rodgers, Colin Campbell, and John Whiteoak, working at Australia's Mount Stromlo observatory under the direction of Dutch-American astronomer Bart Bok, published their nebula catalog in 1960. The RCW catalog is largely an expansion of Colin Gum's 1955 catalog. Although astronomers publish articles referring to the RCW nebulae almost every month, there seems to be few places on the Internet that bring together information on these nebulae as a whole - unlike, for example, the Messier catalog. This is most likely because the Messier objects are visible to anyone with a pair of binoculars or a small telescope. Most of the RCW objects are clearly visible only in long exposure CCD images or photographic plates taken by large telescopes. 

This beautiful nebula, RCW 58, in the southern constellation of Carina, 
surrounds and originates from a special type of star, a Wolf-Rayet star, 
WR40 (HD 96548, WN8).The bright blue star in the middle of the nebula in the above image is WR40. 
The nebula is referred to as a ring nebula, due to its open appearance. 
WR stars are huge, perhaps as large as 20 solar masses. 
They lose mass as they evolve at an incredible rate, producing very strong solar winds. 
They are very hot with temperatures ranging from 30,000 to 200,000 Kelvin. 
There are about 500 of these stars cataloged in our Milky Way Galaxy. 
They give off a large amount of ultraviolet (UV) radiation that ionizes the surrounding 
nebula and makes it glow, allowing us to see it. Most of these WR stars are thought 
to progress to a supernova explosion.
  • For this image, 10 hours were combined in HALPHA, 5 Hours in OIII and another 3 hours in RGB (1 hour each channel). Due to difficulty in stacking SNR in this region, it took several hours between capture and processing.
