Hi
Here are a few shots I took over the last four days from my backyard during some of the coldest winter nights I can remember.
All the shots were taken through a WO Megrez 72 with an unmodded Canon 450D and skywatcher field flattener mounted on a CGE mount without autoguiding. Stacked in DSS with levels and curves in Gimp 2.0 only.
