Last month I took a series of photos of the lunar eclipse. I didn’t have a tracker so I just took photos of the moon moving across the frame until it moved out of frame
I have about 300 photos of the moon as the eclipse was happening and the moon starts from the bottom left corner moving towards the upper right corner
How can I crop each and every photo so that the moon is always centered in the frame? Is there a way I can automate it
The software I currently use is Darktable for windows but I have also used Rawtherapee in the past
Export all of them uncropped (or 10 of them at first, as a test), then align them using Hugin, and in the “Stitcher” tab in Hugin export the remapped images.
Assuming you’re trying to make a video of this? You can use any video editor that supports track motion, like Kdenlive for instance. Import your 300 frames as an image sequence into a cropped 16:9 timeline and use Track Motion to center first and last frames as key-frames. The s/w should automate all in between frames. Now export your video.
