This is a rear view shot
of the new vintage Carton 100mm f/13 refractor objective. There are
three sets of holes in the cell that will be used in a push-pull
arrangement to adjust the tilt of the lens to align it to the
eyepiece at the other end of the tube. This takes a bit of practice,
but the end result will help to nullify off-axis aberrations you can
potentially run into. |
