Comet C/2023 A3 (Tsuchinshan–ATLAS)

I missed the comet for the past several nights due to early evening clouds and even some much-needed rain. The comet is getting fainter and the tail shorter. The magnitude is now 9.9. The first image is a composite of 31 images (5 min 10 sec) and the second one is a composite of 59 images (9 min 50 sec). In the second image there is some movement of the comet head. Also, the comet is moving into a region of the sky with part of the milky way in the background (many more faint stars).
