Three nights with Comet C/2023 A3

Mount Rainier and Comet C/2023 A3 (Tsuchinshan–ATLAS)

The vast majority of my images are taken during the light of day, but that doesn’t mean I do not enjoy the night. So when there was a chance to photograph a comet that hasn’t passed by Earth in 80,000 years, I couldn’t pass up the opportunity.

Comet C/2023 A3 (Tsuchinshan-ATLAS) was discovered in early 2023 by astronomers using telescopes at the Tsuchinshan Observatory in China and the ATLAS survey using a reflector in South Africa. At the time, it was nearly 700 million miles from the sun and already showing a tail. It made its closest approach to the sun at the end of last month, and became the brightest comet to grace our night sky in 27 years.
