I took it with my R8" at F5.6 again with Astro Physics Telecompressor ASTccd67 @ (.69x). I am short 7mm to make it .67x. I used SGPro then DSS in comet mode. From there I took two stacks from comet mode. Option 1 and Option 2. Option 1 makes the stars stationary and leaves a light blob where the comit traveled. And Option 2 Isolates the comet and makes the Stars trail. "And trail they do" and a pain in a but to clean! But I was able to clean up the star trails in PScc and leave the comet in tact with a dark neutral backround.I also used Gradient Exterminator Plugin for PScc, I used "Dust & Scratches" to remove as much of the trails near the comet.

I then Merged the two layers together and put them in Screen Mode and came up with the final Image.

This image was taken around 2 am. The image is of Comet Atlas C/2019-Y4. I used my Ritchey–Chrétien 8" to get larger Magnification of it. On my site I installed a High Zoom in feature so you can really get up and close with this comet. It was imaged in a a Red Zone Bortle 7 Zone.
