Photographing comet C/2023 A3 Tsuchinshan-ATLAS

Photographing C/2023 A3 Tsuchinshan-ATLAS was a challenge.
 
It started with trying to find the comet. Instead of trying to strain my eyes, I just took photos using my camera in the general direction until I found something that looked like the comet, then zoomed in to see if I can get a better photo.


 
In the end, I managed to take two photos that turned out quite okay at a focal length of 400mm, f/6.3, shutter speed of 2s, with difference between the two being one at ISO 1600 and the other at ISO 3200. It was very windy so any exposure longer than 2 seconds didn't turn out very well.

All this in 16 degrees Celsius cold... I didn't think it would be so cold and didn't wear a thicker jacket (the temperature was close to 30 degrees Celsius yesterday, after all), and ended up suffering for more than an hour.
