If you don't mind me asking, how are you taking these?

With a camera ;-)

Actually Jim, I'm using two - my old Canon 10D and my Canon 20Da. Both
fitted with 'normal' lenses and tripod mounted. I also have two
TC80-N3 programmable shutter releases which were set to take 60s
images with a 1s catch-up for the cameras (the 10D needed a reasonable
amount of time to catch up when the sequence was stopped but the 20Da
finished immediately).

The fork in blue was 2s (this was an early shot and the sky was
bright) @ ISO100, f/22, 65mm lens

The other two were both 60s @ ISO400, f/10, 28mm lens. I notice that
one was a 43s exposure. This ould have been because I happened to be
walking past that particular camera and manually terminated the
exposure after the fork. One doesn't want the neighbours shining a
torch up a the window asking "what yer doing?" after somthing like
that ;-)

Out of the total catch, I guess I got about a dozen reasonable shots.

Ah, that matches what I found - in daylight the best I could do was
f22, ISO100 which gave me a 2s (ish, and sometimes less) shot. Thought
I might have been doing something wrong.

The other two were both 60s @ ISO400, f/10, 28mm lens.

I'm guessing ISO400 because you're capturing something that's very fast?

At night it's a different matter of course. As someone else noted, you
can basically hold the shutter open for as long as you want as long as there's
no fixed light source in frame. Well, ok, noise becomes an issue so it's
best to limit the time a bit but even so.

Heh.

Not bad. Thanks for the information.

Doh! I'd forgotten to check the other camera's memory card from the
last session. Not much on it apart from this...

"Not much on it" he says! You can take modesty too far you know? :-)
