>How do you mount slides to minimize ghosts?

I thought I explained this... OK, here it is:  Mount the slides so that
the object prone to ghosting sits at window level.  In the example of
the sunset, the sun should be at window level.  Of course, this screws
up the stereo window with infinity at window level, but, hey, that's
the price you'll pay to eliminate ghosting and that's what happens
if the projector is adjusted, instead of the slide.

How do you put the sun (or any object) at window level?  By sliding
the chips horizontally.  This is how you control the location of the
window and that's what the mounting workshop will (hopefully) teach.
