Yes indeed, very nice data to work with here Martin.
This area looks excellent in narrow band and I think you've done an excellent job of processing.
Now with the rgb data set thrown in for star colour, it's sublime!
Just a hint of noise through sharpening or contrast enhancing to the dark clouds to the r/H side but that would be a nit pick.. as nit picked by Mike
Looks as though the 5" TMB is holding its own I'd say!
All the best
