Popped the Ha on top of the LRGB (again on an RC8). A bit too saturated in red maybe in the Ha regions, but I felt I had to make the Ha data feel useful in the final result !

You know Sam, some might say from a purely aesthetic position it is a little strong but I like it and how cool does it look
lovely to see all those HII regions standing out like that and a good job on the rest of the galaxy too

- anyone found any other galaxies with a lot of Ha regions ?

NGC 1232 and
NGC 253 lend well to the addition of some Ha to make the HII regions pop
