Targets:Orion and Big Dipper
Camera:Olympus Camedia C3030-Zoom

Using a pocket camera for long exposures requires freezing outside temperatures. I tested my camera when it was just below zero degrees Celsius. I could take a half dozen images at a time and then the camera must be shut down to be cooled to surrounding temperatures again. The maximum shutter speed is - and was used here - 16 seconds. Stars down to magnitude 6.5 were visible in the image files.
