Description
Here is my attempt at shooting the Geminid meteor shower in December 2007. Shot using remote interval timer, 30 sec exposures with 1 second interval, then layered using the startrails application [link] and levelled/colour balanced in photoshop.You can see the rotation around the two pole star axes in this shot, unfortunately I didn't capture any bright meteor streaks in the shots.
I know in these sort of shots I need to include something in the foreground, a silhouette perhaps, but all my intentions were for this were to get the meteors and startrails.
This night was very cold, -6 I think, shot at about 12 miles north of Basingstoke. Looked on the GPS and found the location furthest away from any town/large village.
This is the equivalent of a 51 minute exposure time.
You can see Orions Belt at the centre bottom of the frame, with Gemini above and Mars above that.
The startrails application has stripped the EXIF data, so it's here;- 30s @ f3.5, FL 12mm, manual focus using EF-S 10-22mm, Canon EOS 40D, ISO 400, shot 99 exposures between 1:46 am and 2:37 am 16/12/2007

that's really cunning. i've done quite a few star trails, but they've usually been single 30+minute exposures. i'll have to try multiple shorter exposures. where you using the canon timer remote? do you have the noise reduction turned on in-camera?

Yeah definitely try it. You can go all night like this. Then you don't need to worry about overexposing or shadow noise. The stratrails software works (I think) by only sampling the highlights and merging those.
Yeah I was using the interval timer canon TC80N3.
Dark frame noise reduction was off as, the exposures were only 30s at a low ISO. Good luck!

yeah, i've used similar software on my telescope, but never though to use it on my camera. i'll have to give it a go.
