So I'm attending a tech conference in Munich this week - virtually. This means I am keeping CEST, and that lunchtime is 6pm local.

So at lunchtime, I set up my #dwarf3 on the back roof, and let it run for the 'afternoon'.

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.

I ended up with 240 frames out of 300, at 60s per frame - or 4 hours of usable data.

I then ran it through the Dwarflab postprocessing tools, and finished off with some work in Google photos and Snapseed.

A bright star cluster in the top left sits in front of a cloudy nebula that fades to the right. In the upper right is a second, fainter cluster. There is a pair of orange stars on either side of the bottom left corner.

NGC 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.

So we headed down to the beach in the hopes of the Kp index going up and granting us an #aurora but it is not playing ball tonight. Maybe tomorrow.

While waiting, though, we thought we'd run our #DwarfII scopes. I targetted a little #OpenCluster called #NGC6451, or The Tom Thumb cluster.

All sorts of fun stuff going on around it.

$A dense cluster of bright stars, each with six large and two small diffraction spikes, due to the telescope’s optics. They have a variety of sizes depending on their brightness and distance from us in the cluster, and different colours reflecting different types of star. Patches of billowing red gas can be seen in and around the cluster, lit up by the stars. Small stars in the cluster blend into a background of distant stars and galaxies on black.$

#NGC2004 (also known as ESO 86-SC4) is an #openCluster of stars in the southern #constellation of #Dorado. It was discovered by Scottish astronomer #JamesDunlop on September 24, 1826. This is a young, massive cluster with an age of about 20 million years and 23,000 times the mass of the Sun. It has a #coreRadius of 2.85 ± 0.46 pc (9.3 ± 1.5 ly). NGC 2004 is a member of the #LargeMagellanicCloud, which is a #satelliteGalaxy of the #MilkyWay.

Messier 44 – Beehive Cluster
Messier 44 is an open star cluster in the constellation Cancer, containing about 50 stars visible to the naked eye and surrounded by a faint nebulosity.

A #paper published in the #journal #MonthlyNoticesoftheRoyalAstronomicalSociety hints at the existence of several #blackholes in the #Hyadescluster—the closest #opencluster to our #solarsystem—which would make them the closest black holes to #Earth ever detected.

The Pleiades (AKA Seven Sisters, Messier 45, M45) is an open star cluster with considerable nebulosity (Maia and Merope Nebulae are both located within the cluster). Located in the constellation of Taurus, it is one of the brighter night sky objects (mag. 1.6) and easily visible with the naked eye. The Pleiades holds a place in the stellar folklore of most cultures, some may recognize the constellation as the logo of the Japanese automotive brand Subaru (スバル), its namesake.

At approximately 444 light years distant, it is one of the nearest star clusters to Earth, and the nearest messier object. Easily visible with the naked eye, it has an angular size of 110 minutes, or nearly two degrees of arc. At magnitude 1.6.

The cluster is dominated by hot blue and luminous b-type stars that have formed within the last 100 million years. Astronomers estimate that the cluster will survive for about another 250 million years, after which it will disperse due to gravitational interactions with its galactic neighborhood.

This image integrates the best 40 (of over 100!) exposures taken on October 27th 2022.

M11 Wild Duck Cluster

Magnitude 5.8 open cluster located 6,120 light-years away in the constellation Scutum. It was discovered by Gottfried Kirch in 1681. Its popular name derives from the brighter stars forming a triangle which could resemble a flying flock of ducks.
