Trying out the Kase Night Filter, its an interesting filter, even used in this situation which is not entirely what it is designed for, it adjusts colour casts typically associated with city lights and light pollution.

One very positive thing about it is the fact there appears to be no effect on sharpness which is always a concern when stacking more glass out the front, in general all of the Kase stuff I have tried (and own) excels in maintaining sharpness.
