Comet C/2023 A3 (Tsuchinshan-ATLAS) vs Comet C/2025 A6 (Lemmon)

The left shot was taken on October 14th 2024, so between these two photos is one year and one week exactly. We have two tailed wanderers, vastly different in their scale. Considering I've shot them both at 85mm and with full frame cameras - perfect opportunity to demonstrate the vast difference between them!
To expand on it I should also mention the difference in the locations - on the left is Bortle 6+ zone and on the right is Bortle 4 zone. Lastly - the ISO, aperture and exposure for the frames. For the left side it was 1600, f/1.8 and 1s; for the right side it was 6400, f/1.4 and 2.5s. Yeah, Tsuchinshan-ATLAS was vastly bigger and brighter... But to be fair, it was harder to observe in the Northern Hemisphere, due to it's low elevation ^_^
