Okay, that's beginning to sound like an excessive amount. Giving the author the benefit of the doubt, I suppose the ISS could have been processed by stacking and aligning all the ISS frames to create a better image of it, and then that one image was superimposed on the noisier ISS images from each frame. (Similarly for Saturn, which is how planetary images are typically made, anyway.) Not the worst crime, but perhaps not a decision to satisfy the purists.
I still think it's great.
Yes, that could have been done, but then why does the APOD description say that it's a video frame stack? There may have been a miscommunication between the photographer and editor. As it stands, the description combined with the image is indeed misleading and false.
