Views of the day 11 terminator
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.

The second aurora in 2024, just visible to the naked eye.
This image was taken at 00:14 BST. The aurora was visible intermittently between 8pm and 2am. Faint pink and green hues were visible to the naked eye. Cameras revealed much more. In less light-polluted areas the colours were much more vivid.
