The evening that would have been best to observe to Great Conjunction was completely overcast and raining all night. So no chance to see this spectacle. In Sydney, the two planets Jupiter and Saturn were actually at their closest angular separation at 5:22 am on the morning of the 22 nd December. So the evening before would have been about 8 hours before their closest approach, but this evening was only 16 hours after their closest approach so still should not be too bad.
A check on Stellarium confirmed this. Now would the evening be clear? I checked the cloud forecast and it was not that encouraging. But on twilight – there was a gap in the clouds towards the west. So I kept a watch. The planets should be visible a bit after 8:30 pm and they set just after 10 pm – so I did not have a long window.
The gap in the clouds remained, but it was quite low – so I only had time from about 9:15 pm onwards. And at their low elevation, I would be shooting through a lot of atmosphere – and more turbulent summer atmosphere. So my results are very poor. The top photo is cropped from the one below. You can see Jupiter and three of its Moons (Ganymede below, Europe close and above, and Callisto further away and in the same plane, Io was behind Jupiter at the time), and also Saturn below.
