Thanks guys, i'm really happy with the OC shot. Hopefully it will improve once I work out stacking and processing of deepsky shots.
Here's one from earlier in the night:
a wider field Crux/Carina (and a hint of LMC)
- Canon 350D + 17-70mm Sigma lens @ 17mm, f/3.2, ISO800
- 3 images stacked in photoshop (60s, 100s, 120s)
- GradientXTerminator and Noise Reduction
- Levels
That's about it. I'm sure the experts in this area would be able to get more out of my shots

It was a difficult area of sky to image as it was pointing towards Sydney, fairly low on the horizon so there's a lot of gradients and sky glow.
