Two frames from the simulation movie. The atmospheric modeling simulations suggest greater differential motion than is actually observed, and they fail to predict the elongation of the images. We cannot, as the proper pupil observation was not made, rule out the possibility that this may be induced by an unfortunate ocultation of the aperture, however we had no reason to suspect such at the time. This GIF movie is 100 frames of data taken of cows moving around a water tank. This data was also taken with the East Auxiliary of the McMath Solar Telescope at a distance of 10 km.
Contrast variations are due to passing clouds.
The images are now displayed erect, albeit still tilted. The moving cows have been averaged away in the SAA result Cows.2 . The simple co-added long exposure is at left. The principal effect of this processing is smoothing over camera fixed pattern noise, some image sharpening, and stabilization of the atmospherically induced image stretching. Cow at 10 Kilometers Note that the cows are now detected at high contrast, one reflected in the water and one just entering the field of view at the right.
