Poor seeing is always a problem for us located at the base of the Colorado Plateau, due to the onrush of cold air down the 2000 foot slopes into our area for the first half of the night. Shooting clear shots of Mars, now low on in the southern sky has been problematic at best. The image on the top left is an RGB image made from selecting the best of over 50 images taken at .1 second exposure in an attempt to capture the best moments of seeing. Standard brightness and contrast adjustments were applied to make the best of this film like shot. The image on the right is the same image, but deconvolved with 25 iterations per RGB channel with Maxium Entropy Deconvolution. Astra Image 2.0 was used since IT WORKS. I have never been able in hours of trying to get the ME to work in Maxim DL. The improvement is nothing short of dramatic, and while not an Ed Grafton shot, is the best I've taken so far. Mars Previewer is used below to show the central meridian map of the image, with Syrtis Major clearly visible to the left of center. Rich Jacobs fine image to the lower right which was taken in much better seeing a few nights before is inverted to match my image, to show the markings after maximum entropy are not "invented".
