#Comet2023a3

0 posts0 participants0 posts today
Mike LeeA stunning moment from October 14, 2024—comet C/2023 A3 Tsuchinshan-ATLAS blazing across the twilight sky at Eagle Lake in Lassen County, CA. Captured from the breakwater at Gallatin Marina during nautical twilight, with an 85% moon lighting up the scene. That tail spanned an estimated 15° across the sky!<br> <br> The patrol boat in the frame belongs to the Lassen County Sheriff’s Department—right next to the dock I’ve launched from many times chasing Eagle Lake’s famed rainbow trout. Shot at just over 50mm on a full-frame camera, this view is pretty close to what I saw with my own eyes… just brighter thanks to the 8-second exposure.<br> <br> Nature never disappoints. 🌌🚤🌲<br> <br> <a href="https://pixelfed.social/discover/tags/Comet2023A3?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Comet2023A3</a> <a href="https://pixelfed.social/discover/tags/EagleLake?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#EagleLake</a> <a href="https://pixelfed.social/discover/tags/Astrophotography?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#Astrophotography</a> <a href="https://pixelfed.social/discover/tags/NightSky?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#NightSky</a> <a href="https://pixelfed.social/discover/tags/LassenCounty?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#LassenCounty</a>

Kevin Freitas<p>Tues. night in Seattle was super clear so I got out with my Dwarf II to image Comet C/2023 A3 (Tsuchinshan-ATLAS). This is a stack of about 95 x 8 second frames and I’m super excited I got the anti-tail!

De komeet is genoemd naar het 紫金山 observatorium waar de komeet ontdekt is. Chinese pinyin spelling is Zijinshan. Geen idee waarom die ouderwetse spelling gebruikt wordt. Verwarrend is het wel. Twaalf jaar geleden was ik op 紫金山. Hieronder twee fotos van de mooiste en minder bekende attracties van Nanjing.</p>

Mark McCaughrean<p>A clear night over the Odenwald for once, so grabbed the chance to get perhaps a final glimpse of Comet C/2023 A3 (Tsuchinshan-ATLAS). </p><p>It’s still there, but faint, &amp; even in the absence of last week’s moonlight, the light pollution over Mannheim was enough to make it invisible naked-eye.</p><p>But I got some DSLR shots which’ll be better than the IPhone’s funky night mode algorithm.

Quopas<p>Went out to the Muir Beach Overlook on Saturday night to watch the sunset and see comet A3 Tsuchinshan-ATLAS.
