Mercury imaged under difficult conditions but relatively good seeing. A total of 20 video sequences was captured during breaks in fast-moving clouds, and a gusty breeze shaking the telescope resulted in a lot of planet-free frames. The seeing in the clear periods was not bad, and the proportion of usable frames was about 0.7% which is better than average. The final set of frames was chosen using a mixture of software and manual selection. Comparison of the final image with a blurred version of one based on Messenger data shows good agreement of many of the albedo features.
