I took this the night before last at about 5:00 AM CST at my observatory - www.hcobs.org
The bortle reading was 21.6. I used a Canon R5 (unmodified) at 3200 ISO with a Canon EF 500mm f4 at f4. The camera/lens was mounted on an Orion EQ-G mount and I used a Lacerta MGEN 3 for autoguiding and camera control. The exposure was 60 seconds since the comet was moving about 5"/minute. I used canon DPP for Raw conversion to 16 bit tiff. The I used Photoshop CC and Luminar AI for cleanup.
