Here is an image of SH2-170. I found this object to be pretty dim, so I did an HA exposure and then pretty conventional (short) RGBs for starfield color only. I was pretty sure that If I was to try to get nebula color in the RGBs, all my stars would be overexposed to white. I used the "extracted" nebula from the HA to do a false color "lighten" combine to the red channel.
