Nice work Andy, that's the way to do it, produce several combinations to suit all tastes

although this way highlights different aspects in the data too. Overall, each of the three versions are kinda nice in their own way (err?..except of course the Narrowband

), for me I guess the HaRGB version most appears the way I think the Trifid
should look but I recon you will get as many opinions and tastes, as there are ways of combining the data
The data looks to be of good quality though

PS the NB version isn't that bad
