Despite having had and enjoyed my Canon 30D for 7 months (and 8000+ images!), I am still learning some of the technical aspects. Last evening I wished to take a time-exposure of a very clear starry night but could not find a mode for having the shutter open indefinitely. Am I 'thick' or is the max shutter speed 30 seconds? I was hoping to use something like 5 minutes.
Cheers
Ted
