Mike, my guess is that keeping the entrance pupil stable ensures that there
is no undesired change in subject size on the in-focus image. But keep in
mind that I didn't even complete the sophomore year of my focal studies.
Thanks for the links to the setup used. I am tempted to describe them as
'inspiring' - but I don't imagine I would ever be inspired actually to do
what Charlie Krebs did. I'll stick to dreaming.

PS What _is_ a sophomore year?

Hi Chuck,
Not quite , but pretty close-----
I was able to find the images as I had forwarded them to Jeff K.
Perhaps you could ask Dr. Focus why keeping the entrance pupil stable and
moving the cam would enable an easier stack.
Jeff had a suggestion of using a T-mount lens on a board connected with
light proof cloth as an alternative to destroying a nice Zuiko.

My recollection wasn't too far off after quite a period of time. This is the
set up that was used:

Stack 'em near and far, Mike
