Hi,
You use the bulk mode. Also, need a remote control to hold the exposure and also to reduce vibration.

By the way, according to Canon, a full charge battery can take up to 2.5 hours long exposure in 300D! :k-shock:

Have a nice day.

*bulb mode. i think problem wif most cam is battery power is needed to keep the shutter open, so there is limit to length of exposure, unlike those older camera which do not run on battery.

Just for info, if you get a generic replacement battery, eg from Cathay in Peninsula, you can go even longer without having to change the battery. I routinely run ~4hrs on the 300D before needing to change.

Hi,
Anyway, I don't think this is a big problem. Battery low, just change one... It won't cause any problem, unless you are doing a long exposure of more than 2 hours... which is very unlikely. If you really need the extra long exposure, just use a battery grid which can put two battery in it or use an adapter to connect to an external power source.

Have a nice day.

Hi Weixing,

Photoshopped your startrails for aesthetic effect. See if you like it.

Happy new year and congrats on your new aquisition (300d)!

I remember reading before a technique of taking star trails by taking many 5 min exposures and stacking them together using the "lighten" function in photoshop. You might like to try that one day.

Cheers,
Chris
