    I used a Canon EOS RebelT7i 'mod. UV-IR @ Hutech' thru a 75-300mm Refurbished $85.00 Canon Lens @ 200mmfl piggybacked while guiding on an Astro-Physics 1200GTO Mount for four 7nmHa 215secISO6400 and SII 335secISO6400 and two UHC 395secISO6400 and as CR2s I put them in MaximDL Pro V6.20 and did a regular 'ConvertColor' and 'KernalFilter-Median5x5' and Bin2 ... then with just a single image of each Ha , SII , and UHC I changed them to 'Mono' and then opened the 'ColorStack' and made a single Ha image 'green' and single SII image 'red' and a single UHC image 'blue' and pressed the 'Align' and from the droplist I selected 'Auto-star matching' and pressed OK and then the images are processed and then press the 'ColorStack' command's 'OK' and the image will appear and 'screen-stretch' is needed to show the false-color' like the Hubble Palette colors ... this is the first time I tried this but it seems easy so far .?. I have more of each image to stack this way and also H-beta but that way didn't work yet . The purpose of this false-color' is for the 'Great Cygnus Wall' in the area of Mexico's East gulf shore line .. so the Lens set at 250mm or 290mm might shoe the 'wall' closer .x

    Its a nice image however if i could suggest, you might try to even the histogram levels just a bit. i took your image and made the Blue, Red, and Green histograms even out and dropped the top end down a bit via a screen stretch to bring out the nebula and remove some of the skyglow. This made your image really pop. See the attached file.

    thanx... I'm experimenting with the filters and a Lens gets the photons fast to see what happens .
    I have another example about how I did it .
