How to position a Lunt Blocking Filter

In the process of taking parts of the Lunt LS50THA apart, I wasn’t sure how to position the blocking filter.  Both sides had the same screw fitting.  So, I emailed Lunt and got clarification.  One side has a blue/green tint.  That side should go towards the scope.  The other side has a red tint and that goes towards the eyepiece.
