Playing around with astrophotography. This is a stack of about 580 dark-subtracted exposures from a stationary mount, 0.3 seconds each, ISO 1600, Pentax DA* 300mm f/4 wide open. Trailing of stars is still apparent. I'm impressed by how much detail even a single exposure contains. It would be nice to get the O-GPS1 accessory to extend the individual exposure time to several seconds without star trails.
