While you're here, how about checking out the Astronomy Book List ?

Hi,

I have been told that the distance of the EP/CCD from the visual back will
affect the optical performance of a LX200 10". Is this true? If it is how
does one determine the best setup.

The dialog went something like: The distance between the primary and
secondary will affect the amount of 'correction' in the optical path and
the optimal placement of the EP will vary from scope to scope.

Any comments or insight is welcome,
Jim
