The AVI file is better quality than the MPG. The 10 fps video is a stretched, blurred (to remove pixel defects due to Philips driver interpolation problems), sharpened, and highly compressed copy of the original AVI captured at the telescope. Observation details are the same as for the Jan. 27 still frame shown above. Orientation of the movie is South up, West to the left.
