I've tried to use the Timelapse function a few times for Astrophotography work but I can't seem to get it to work. I set my camera up for a 60 second exposure, set up Timelapse for 30 shots with a 1 second interval and then attempt to set it off. The camera instructs me to hit the shutter button but after doing that the LUMIX logo comes up on the LCD and the camera turns itself off. I have had marginally more success with faster shutter speeds for normal shots but the camera has crashed a couple of times. Has anyone else had this experience?
