Orionids meteor shower - What lens would you recommend

Time to put on a late nighter tonight.....or an early morninger depending on how you look at it I guess.

Ok details. Canon 300D (or 20D depending on if I want to muck around later getting the colour balance right ) probably mounted piggy back and tracking on my G8. Or maybe not. I've never really tried for meteor showers before. Would it be more like lightening? Use a tripod, keep the lens open until trailing would be noticeable, terminate the shot and start the next one.

Anyway, my real question is; what lens would be suitable. I guess it depends on the distance that the meteors are reaching across the sky. I have a 17-40mm @ 17mm (54 X 81) but would that be too wide and make the meteors appear too small and just streaks? Or would I be better with my nifty 50 (17.2 X 26) or my 85 (10 X 15.4) and go for more size on the elusive suckers?

just be happy you can image oh photon king - its raining here, use the 17 lens at 30 second intervals - and mount on tripod. then you can use STARTRAILS to create a time lapse later - and a startrail complete with meteors!!

Well I think it was a bust last night. The Orionids didn't put on much of a show up until 1:00 when I called it quits. There were a few meteors with one in particular getting a real "Fwooarr!!!" from me but generally it was pretty quiet. The good one went from about 20 above the northeastern horizon to almost the southwestern horizon and had a lit up tail about 90 long overall. It was really spectacular.

I ended up using the 17 - 40 @ ISO1600 with 45 sec exposures in continuous shooting mode, from about 10 pm to 12:30am. I should be able to do a great animation of Orion rising.

It's OK Dave. But unfortunately my focus wasn't quite right and 45 sec was a bit long (though it shouldn't have been :shrub: ) . I doubt if I'll be uploading it though. 109 images creates a fairly hefty animated gif
