The seeing was quite good, yielding some good frames in the video. Bright Moon nearby.

8" LX200, x2 Barlow giving about f/25, Toucam webcam at prime focus. Best 135 of 1200 frames at 10 fps. Gain set to minimum possible to get a usable image. Aligned, stacked and wavelets in Registax. Noise reduction Neat Image. Gamma 0.75.
As above, but x1.5 resampling applied before alignment and only best 100 frames used.
