A list of bright deep sky objects that is supplementary to the Messier List, which missed several objects worthy of listing – and listed nothing south of 35° S.
The dates of the highest passing of the objects are an approximation.
The first fourteen items (C1-C14)* are not visible from Macarthur’s 34° S latitude.
