I hope your suggestion works, it's an easy fix.

Hi Kosh,
That's good but it's not that easy -
the distance of 55mm is recommended but will change by ± 1 mm
or maybe more - depending on your scope.
That allows the MPCC to correct for different f ratios.
You may need a set of spacers to try.

cheers
Allan
