[AZ-Observing] Re: Time-Lapse: One Hour at Five Mile Meadow

Tom, there is one more way to take time lapse with a
Canon - put the camera in burst mode, then hold the
shuttter button down with say a piece of duct tape or
use the cheap remote.  If the exposure is set for 30s,
it will burst 30s exposures forever.
