Canon 400D, Canon EF 24-105mm f/4 L lens - 7 exp (1/5 to 3.2 second), f/16, ISO 100

This was the sky outside of my study last night in HDR form. I used Photomatix to blend 7 exposures taken at different durations. I've tried HDR photography before with Photoshop but this is the first time with Photomatix.

I'm happy with the result but my tripod was at full stretch and it slipped slightly during the sequence which Photomatix then had to correct for so the image loses a bit of definition.
