Saturn after occultation by the Moon

This composite photo shows the planet Saturn after the end of occultation, when it became visible again in the evening sky. Above you can see the southern part of the Moon, very rich in craters, and the bright spot near Saturn is 85 Aquarii, a star of magnitude 6.7 distant about 560 light years. To make this image I first shot Saturn, just before the event, then the Moon with two different exposure times and finally I composed the results using a frame taken from the original shot to position the celestial bodies in the correct way.
