Obviously I dont know either but I suspect that Adrian might be on the right track actually.
Looking at the pic with anomalies, one can see that there are numerous reproductions of the same couple of stars (bright above faint below) but all over the place, not explicable by a mechanical error. Also not explicable by anything that would have happenned and affected one component of the image while the rest (on a time line) is unaffected), also cant be explained by tracking errors/clouds losing/regaining gide star as the composition of the duo of stars is too perfectly matched throughout the picture to be the result of multiple "mini" imaging sessions,as it were, if the guide star was lost, regained (imageing properly) lost regained (imaging again possibly in the different area of the final picture) etc...
in my opinion, and I say this unabashedly, it's pure guess work here, looking at the pic I suspect a digital/electronic process occurred not a mechanical one.
If I was standing in the observatory right now I would say something along the lines of ..." ...and the guilty party is in THIS very room..."
my eyes would glance at the ST7 and the computer/laptop? hoping one would break out into a long soliloquy of confessed sins a la "Ok it was me...I went haywire..."
I just cant help but think it's digital/electronic.
but the short answer is : "i dont know either"...(suspect a digital/electronic process not mechanical)
