Since I see there are some users using this filter, I have the following question.
I'm trying to get flat frames with an Optolong L-Enhance filter. Without the filter I get good quality flats, but with the filter the histogram shows the three color channels quite separated. I guess is normal in such filters, but the case is that I don't notice any difference between applying these flats and without them. So my guess is I'm doing something wrong.
Sample:
The color of your flats should have no bearing on how well they work. In fact, meddling with their coloring can artificially increase noise in your flats (which then get imprinted on your calibrated lights!).
