rdm<p>So I'm attending a tech conference in Munich this week - virtually. This means I am keeping CEST, and that lunchtime is 6pm local. </p><p>So at lunchtime, I set up my <a href="https://aus.social/tags/dwarf3" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>dwarf3</span></a> on the back roof, and let it run for the 'afternoon'. </p><p>My target was Messier 6 aka NGC6405 aka "The Butterfly Cluster". There is some very nice nebulosity right next to it. so I framed things a little off, and also got the smaller open clusters NGC6383 (aka NGC6374) and the tiny NGC6404.</p><p>I ended up with 240 frames out of 300, at 60s per frame - or 4 hours of usable data.</p><p>I then ran it through the Dwarflab postprocessing tools, and finished off with some work in Google photos and Snapseed. </p><p><a href="https://aus.social/tags/nebula" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>nebula</span></a> <a href="https://aus.social/tags/OpenCluster" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OpenCluster</span></a> <a href="https://aus.social/tags/M6" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>M6</span></a> <a href="https://aus.social/tags/NGC6383" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NGC6383</span></a> <a href="https://aus.social/tags/NGC6406" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NGC6406</span></a> <a href="https://aus.social/tags/Astrodon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Astrodon</span></a> <a href="https://aus.social/tags/Astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Astronomy</span></a> <a href="https://aus.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>astrophotography</span></a> <a href="https://aus.social/tags/Scorpius" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Scorpius</span></a></p>

DüttNGC 6791 ist ein lichtschwacher aber sternreicher Offener Haufen in der Leier. Die Entfernung von 6791 wird auf 13000 bis 17000 Lichtjahre geschätzt, das Alter auf etwa 8 Mrd. Jahre. Damit ist er einer der ältesten Sternhaufen in unserer Galaxis und seine Sterne sollten metallarm sein- was sie aber nicht sind. Aus diesem Grund gehört NGC 6791 zu den am häufigsten untersuchten Sternhaufen. NGC 6791 wurde im Dezember 1853 von dem deutschen Astronomen Friedrich August Theodor Winnecke entdeckt.<br>
