I set up my 400D doing 30s exposures every 34 seconds, F3.5, ISO 800, fully wide ( 18mm*1.6 so 29mm equiv ) when I went to bed - it took 247 exposures looking east, from 0027 to 0257 before the battery packed up in the cold of the conservatory. I figure I was capturing 88% of that period of time on film...a total of 132 minutes of exposed time. They're great images...you can watch Leo slowly rising - M44 is very visible - getting stars down to 7, 7.5, maybe 8. Not the ideal pointing, but the best I could do from the conservatory given that I wanted to keep everything inside....a few banks of light cloud popped through every now and again, but overall, I'm fairly sure any Leonid that I would have noticed by eye I would have seen on 'film'.. I know I didn't 'get' the peak....but even 5 per hour would have seen me get a couple at least...
I have ONE streak on film....and it's not a Leonid.

I think the Lion had a night off, and I know Stu didn't fair much better in Kendal.
