Maybe combine the narrow band and green to take a slice out of the green but cut off the ends of the spectrum? (just off the top of my head)
I could see the active region around midday today with a small associated filament, but the spot was gone. The spot was still there yesterday. I had to look hard to find the AR but once I knew where it was it stood out well - still honing my observing skills - there's more detail to be seen with the Lunt vs the pst. (working at about 30x mag)
