  1. 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.

  3. 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.

  5. 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.

  9. We setup my camera on one of the Buffalo Astronomical Association's telescopes during the Buffalo Audubon's Trick-or-Treat Hike event on 10//19/2024 to capture comet C/2023 A3 (Tsuchinshan-Atlas). Here’s my process of the data. 112 subs at 15 sec each for 28 minutes of total exposure.

  14. 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.

  18. 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…"

  22. I was able to squeeze a few good photos of Comet Tsuchinshan-ATLAS out of my setup tonight. But it grows increasingly dim and hard to separate from the "noise" of the night sky.

    Still thankful for the opportunity to document astronomical history.

  26. Tonight, Comet Tsuchinshan-ATLAS contrasted with #Autumn #foliage over #TrumbullCT.

    It was *much* harder to photograph the comet tonight, either because it is dimmer or because there was more light pollution. But I am happy with the few shots I managed to get.

  30. Photos of Comet Tsuchinshan-ATLAS taken tonight via my Canon EOS R7 using my Canon RF 24-105mm f/4L lens.

    The first is with the F-Stop minimized and the second with it at normal settings. Both enhanced a bit with Luminari Luminar Neo.

    I think I am learning what works best for my setup. I am much happier with these photos than the ones last night.

  34. Last night my daughter & I went back to her high school campus. A teacher opened up the school observatory to view the comet. The telescope view was underwhelming.

    I also brought along camera & tripod to see if I could recapture the magic from a few nights ago.

    The town is highly light polluted & the comet has dimmed. I could not find it in the viewfinder, so I shot on instinct. This is the best I could do. Comet is upper left.
