On the same theme .. how do people do their star trails ?!
I always just leave the shutter open for 10-40 minutes, depending on boredom etc... but I've read recently this can cause the shutter to overheat. The Nikons I believe have a digital 'motor drive' where you can set it up for x exposures at x intervals on the camera itself...
Canon's don't have this (Trev, don't you say a f**king word sunshine :rasp so I guess the only way to do it properly is laptop + Canon's software set at intervals ?
Finally someone has made a star trail stacker for OS X .. so I want to try this soon....!
Suggestions / hints / tips etc would be welcome. Sorry for crashing the thread
