The night was really bad. I was going to image with the EOS but couls not get the webcam to work on one cable, as I usually do, it needed both. Hence a quick switchover of equipment in the dark.
The image could have been a lot better. It was foggy, wet, dew on everything, hairdryer working at full pelt.

Nice image, im suprised you got anything out of last night, the sky glow i saw put me off of even attempting any imaging, I've tried crab nebula before but came up empty handed, i think it might be the poor Ha sensitivity of the EOS
