Re: star trail
Tim,
I have a homemade involameter. You can just use a watch or a stopwatch. Generally you want to start the next exposuer within a few seconds of the previous one.

Re: star trail
I know this is a digital forum but from what I have read of film, it seems to be a better choice for a 5-6 hour shot based on no sensor to heat up. No I dont have experience with this, so I could be completely wrong.
If film would be better it would give me a reason to get the EOS 1V and try out some 5-6 hour exposures [].
But for an adapter for the 40D, I found a website with some info on that http://www.astronomiser.co.uk/canonpower.htm
Thank
