Ektachrome at 1/250s and f11....try photographing stars with that setting - or even with a digital camera...stars are many orders of magnitude dimmer than the moon and earth in full sunlight, flim or digital photography don't have the dynamic range to show both at the same time. To properly expose for stars you need many seconds of exposure, and a tripod with a motorized equatorial mount (or high ISO film that will be less resolution)
