They were taken with a 135mm focal-length telephoto lens on a digital SLR camera (at f/2.8). Last night's was a 20 sec exposure (one of a sequence I haven't had time to reduce yet).
Last night's image also shows two star clusters. NGC 6633 is the group of stars at the top, and IC 4756 is to the upper left of the comet. Both are open star clusters.
The sky was clear last night and I was able to image Comet C/2023 A3 Tsuchinshan-ATLAS, which has faded greatly over the past few weeks.
On the left, Comet Tsuchinshan-ATLAS imaged yesterday evening (Thursday, 8th November), the first clear evening in three weeks.
On the right, the comet with the same lens the previous clear night (17th October).
The images show how much the comet has faded and reduced in angular size over three weeks.

Description: It's been a couple of weeks since my first glimpse of Comet C/2023 A3 (Tsuchinshan–ATLAS) in Yosemite and in that time it has grown dimmer. So dim that this weekend in Canyonlands National Park and Dead Horse Point State Park we could only see the comet in photos. or fool ourselves that indirect viewing
The skies cleared, so I was able to catch sight of Comet Tsuchinshan-ATLAS again, with assistance of a tripod and a remote trigger to avoid shake and blur.

Woohoo! I broke out the tripod and was able to get some more photos of Comet Tsuchinshan-ATLAS over Trumbull, CT.

The comet is so very dim now. This is probably the last night for useable photographs.
Thank you, Comet Tsuchinshan-ATLAS, for so many nights of wonder and delight. We live n a universe of miraculous beauty.

Every night, I wonder if it is the *last* night I'll be able to photograph Comet Tsuchinshan-ATLAS. But it showed up again tonight with *just* enough brightness.
"But a thing isn't beautiful because it lasts…"
