Also referred to as NGC6559.
I took this one a while ago. Astrophysics RHA 305 F3.8 scope and FLI Microline 16200 camera ( one of the first images I took with it).
I added more data at the time after I first processed it as I thought the image was a tad flat. This lifted it.
Its about 11 hours of data.
I also tried adding some TEC180 FL data I had but it didn't really overall lift the image and the tracking on the TEC data was slightly off.
Its an interesting processing here in that I did have quite a bit more data but when I processed it all I couldn't get it as good as the smaller amount of data. Go figure.

Here is another version of HaLRGB designed to get the softer nuances. Its more in that direction.

This is 17 hours total exposure, 290 mins of Ha, 80 mins luminance 210 red, 230 green 210 blue.
Also here's a version of just RGB only (10 hour and 50 minutes worth):
