Not sure what you're meaning about Focusmax always using luminance.
I just manually select the filter in Maxim and the run Focusmax. Watching the log, it appears to me that it is focusing with the selected filter.
CCDC definitely lets you select which filter it will focus with.
It's not just the filter glass being par focal, but the whole imaging train - I'm using a fluorite doublet, so there will be more variance in focus point between wavelengths than a triplet. I have seen Mike comment that there are focus differences between filters even with his big AP scope - high end filters, high end scope.
