The sky conditions were remarkably good this evening though with some patchy cloud. The jet stream was slow for once after stormy weather yesterday and the planets showed plenty of detail. I was lucky to catch the Great Red Spot on Jupiter with a simultaneous shadow transit of Europa at 22h10.

The ASI662MC has small 2.9 micron pixels which give excellent resolution, especially in a long scope such as the CC. The 10th Jan was the stablest and most transparent evening we have had for weeks if not months and the Moon was really high at over 65° in altitude. The 12th was less clear but still gave a really good view of the full Moon.
