I was away from the city this weekend and the sky was clear enough for some star trails pictures, so I took a few.

This one is 20 minutes



And this one is 25 minutes



The sky was not totaly dark since there were some houses with big flood lights nearby. That's why the trees are visible in the first picture, I like the effect.

I wasn't sure if I was going to try shooting multiple shorter exposures or a single long one but I settled on on long this time around. Next time I'll probably try short.

Comments are welcome.

Very nice photos. I will have the same opportunity to take star trail pics in about three weeks time. I'd love to know a little more info about your exposures? Did you use the in camera noise reduction? jpeg? raw? ISO? focal lengthh? (wide or tele?) aperature?

thanks, sorry for so many questions. I probably won't have many attempts and want a good starting point for my exposures.

Although I haven't used it there is a bulb mode if you use fully manual.

Dial the shutter speed below 30s and it will switch to bulb. Then the shutter will remain open while you hold the shutter release for as long as you like.

Go to Tv mode and turn the dial up to "BULB" mode. The shutter will stay open for as long as you want it in this mode. But you have to manually hold the shutter in. This will of course bring camera shake. What you need is a remote shutter release that locks up so you don't have to hold/press anything. I got the Canon RS60E3. This is it here:

how do you get 20 minutes exposure? isn't it limited to 30 seconds
on DRXT?

Just wonderng if you noticed a lot of noise in the pictures. Was this shot with the XT?

Yes I shot with the XT, ISO100 and the noise is acceptable. In these pictures I didn't use any noise reduction. I did some adjustements in photoshop on the raw image and that's about it.

I was a cool night also, and I've head that cold tempertures help to reduce the sensor noise, so I guess it helped in this case.

Thanks.

Details:
Rebel XT
ISO 100
No noise reduction
RAW
Focal: 17mm

It's pretty simple really. Point the camera to the sky, try to keep some objects in the frame (trees, houses, etc...) and use a wired release and lock it open in bulb mode. Use your watch to time the exposure.

What did you use for Aperature settings? About "how" long did you have the shutter open to get this effect?

Thanks, i am really interested in trying this!

I love my 28-135 IS USM!!!
 
Yes you can do the same thing with the wireless remote. Press it once to open the shutter, again to close it.
