Best 1k/5k with the QHY 458C and the Spooner-Ricks 6" f/8 at f/12.
This is 37x300s with the Player One Uranus C Pro through my TS Optics 102SD f/11 and the Astro-Physics Telecompressor (CCDT67), which reduces the scope to eff. f/6.93. This was taken from my backyard, and my subdivision lately installed new >4k streetlights with no shielding---a disaster for astronomy. I'm doing my best here and still glad I can do something.
These were taken with the old Canon T3i and a zoom lens on hand, over a drainage pond. I spotted the comet first in an image taken of the area SkySafari indicated the comet would be found. I took about 160 images, and these were some of the best. The camera was stationary on a tripod. The images would have been much better if the camera were tracking.
This one was a phone shot with the Pixel 4 XL, taken on Wednesday Oct. 16 when I was showing the comet to some friends:
