Taken during Qld Astrofest last month, this is a 2 frame mosaic of Scorpius taken with the 450D and a "nifty 50" lens at F/5.0. Each frame was 1hr of 10min subs taken at ISO 400.
It's taken me some time to get around to doing matching 10min darks (my wife got quite a surprise to find the Canon clicking away in the fridge one night recently around midnight

)

This is probably my fav constellation dating back to first recognition of the brighter stars a long time ago, so pleased with this one. Thanks for looking.
