A mix of single exposures with different exposure times. 18 frames at 360 seconds, 11 frames at 180 seconds, 6 frames at 300 seconds. The reference frame was a 180-second exposure taken with a green filter. Total integration time is 2 hours and 51 minutes. There was no particular plan behind this—I shot it as an experiment, and something came out of it anyway.
