Mercury is now moving away from the Sun and its phase is decreasing. The seeing on this occasion was relatively good, on the better side of Ant III, so I was able to be more selective in the quality of frames to stack yet still include a good number. The verification images agree well with one another, giving confidence that the features seen are genuine, as confirmed by the reference images from Stellarium.

Approx 70,000 frames captured; frame selection using Registax and VirtualDub; stacking and processing in Registax and Iris.
