Please see revision C!
It is an animated GIF timelapse that shows how the shadows from the crater rim proceeds across the floor of Fracastorius crater for three hours during the night of September 25.
It was created as follows: I captured 2 000 frames once every ten minutes from midnight till 03:00. From each of these videos the best 15% was stacked in Autostakkert. The resulting 16 still images were aligned using the Hugin panorama stitcher. These images were then added as aligned layers to an image in GIMP and cropped to a suitable common size. From GIMP the layers were exported to separate images and sharpened in Topaz. Then I created a 15 s long time-lapse video from the 16 still images using the video interpolating app "Rife-app". This mp4 video file was then converted to a GIF animation in Filmora.
I would have preferred to have done this with a Barlow lens and a longer focal length. Due to a polar alignment problem the tracking was too poor to use a longer focal length.
The idea came from this post over att Reddit:
