Here is an image of the Bubble Nebula (NGC 7635) along with Open Cluster M52 also known as "October Salt & Pepper."
This is 90 minutes of Ha, 30 minutes of luminance, and 20 minutes each of RGB. Ha and Lum were unbinnned, RGB binned 2x2.
While I am happy with the detail in the image, I feel that the color is off. I think I need to re-do my processing using Gendler's or others Ha methods to combine the data. I added the Ha to the Luminance and to the Red, hoping to have color balance and red while not limiting the Ha data with the relatively noisy red data. That will have to wait for another day.
Thanks for looking.
