I get a little nervous when we suggest putting a filter behind optical
elements (when the subject is the sun).
Focused (or semi-focused?) sun rays might increase the heat build-up
in the dark glass of the filter which could lead to the filter
cracking/breaking.

Just recommending an abundance of caution when messing with things
that might put eyesight and expensive cameras at risk.
