Comet C/2023 A3 (Tsuchinshan-ATLAS) on 13 Oct, as seen from the Sacramento mountains of southern New Mexico. (Elevation 9,000 feet.)
Closeup in bright twilight using a 400mm lens. (Stack of 18 5-second exposures.)
1st image is a moderate crop of the entire frame and shows the inner tail.
2nd image is a tighter crop with the histogram manipulated to better show the central shadow in the inner tail...a long thin black stripe.
A few stars are also visible. They are trailed because the comet moved compared to the distant stars.
3rd image is a very tight crop with additional image processing.
Image was converted to grayscale, re-sampled to 200%, and unsharp masking applied to bring out other features close to the nucleus.
It appears there is a spinning jet visible. (As the comet gets higher in the sky, high resolution imaging over a longer time span will show us rotation behavior of the comet and its jets.)
