I took this link from wikimedia. It shows the immediate area around the Southern Cross, Crux.
The various objects are listed with their NGC number (new general catalogue). The yellow discs are Open Clusters, the round discs with a cross are Globular clusters. The red ovals are galaxies. Green blobs are nebulae and the round green blobs with an external cross are Planetary nebulae.
The Jewel Box is 4755.
Eta Carina is the huge green blob to the right of Crux. The two really big and bright clusters I mentioned near Eta Carina are 3532 and I2602, the Southern Pleiades, with 3255 another beauty.
Centaurus contains the biggest Globular Cluster in the sky, Omega Centuri, 5139. I can even see it as a faint, fuzzy 'star' from my home it is so bright. You can't mistaken its bright fuzziness in binos. Extraordinary in any scope 4" and over.
With your binos, have a shot at the galaxy 5128, also known as Centaurus A. It is an edge on spiral galaxy that resembles a hamburger in appearance. You will definately see it in your 70mm binos. I've seen it through a 30mm finder, though at a dark sky. 70mm binos should reveal it in Sydney skies. Have a shot.
The star closest to us, other than the Sun, is in Centaurus- Alpha Centuri, also known as Rigel Kentaururs and Rigel Kent. It is actually a tertiary system, meaning that it is not one star, but three that orbit around eachother. The two brightest can be easily seen as even a modest little scope should be able to 'split' the aparent single star. The third member of the group is very faint and is actually very close to the boundary with Crux, if I remember correctly. It requires more specialised maps to find and identify. Alpha Centuri lies 4.3 light years from us. The Sun is 8 light minutes.
