I finished a nice year of astrophotography with another @astrobin_com debut - the apparent galaxy pair UGC 3574 and UGC 3569. bit.ly/4lB3t68 🔭#astrophotography 🔭📷

Arp 206 a.k.a. NGC3432 is an edge-on SBm galaxy which is interacting with UGC 5983, a nearby dwarf galaxy. bit.ly/4lB3t68 🔭#astrophotography

4MOST - Ein neuer Blick ins All. Matthias Steinmetz ( @galacticrave.bsky.social ) von @aippotsdam.bsky.social & @unipotsdam.bsky.social zu Gast bei #TonspurWissen, dem #Podcast von @leibniz-gemeinschaft.de & Rheinischer Post. 👁️🔭🌟 pod.fo/e/364503 #Astrophysik #Astronomie #4MOST @4most-eu.bsky.social

🌌 Das Universum – unendliche Weiten. Wie schnell es sich ausdehnt, beschreibt die Hubble-Konstante, doch ihr genauer Wert ist umstritten. 💫 Mehr dazu im Vortrag von @galacticrave.bsky.social aus der Reihe der virtuellen #BabelsbergerSternnenächte ✨. Jetzt reinschauen: youtu.be/0wfPdhJWMTM

Arp 283 is a pair of interacting galaxies (consisting of NGC 2798 & 2799). The yellow/blue color contrast is nicely mirrored by two (neighboring bright stars rounding off this ensemble quite appealingly. bit.ly/4lB3t68 🔭#astrophotography

We are continuing to expand our efforts to protect the night skies. ESO signed an agreement with the IAU's Centre for the Protection of the Dark and Quiet Sky to become a contributing partner. https://www.eso.org/public/announcements/ann25010/ 🔭 🧪 📷 A. Daniels (SKAO)

Cosmic contrasts: the planetary nebula IBHASX J055226.2+323724 is located in the 500 million year old open star cluster M37. It is only the 3rd example of an association between a PN and open cluster! It seems to be the oldest PN found so far. bit.ly/4lB3t68 🔭#astrophotography🔭📷

NGC974 is a SB galaxy located in Triangulum. The distorted spiral arms hint towards interaction with NGC969. Other gals in the pix: NGC 970, a companion of NGC969; NGC978 with PGC9823; NGC971 is a star that is in NGC by error. bit.ly/4lB3t68 🔭#astrophotography🔭📷

A trip to the Paranal Observatory allowed me to take this WF shot of the Milky Way with comet C/2005 R2 (SWAN) few days after it passed M16. bit.ly/4lB3t68%F0%9...

2/ If you want to learn more about 4MOST, head over to the ESO Blog to learn about: 👉 the technical challenges of observing thousands of objects simultaneously 👉 the scientific questions @4most-eu.bsky.social will address www.eso.org/public/blog/... 🔭 🧪 #instrumentation

First Light for 4MOST - what an experience! Paranal Observatory is already a magic place on its own right - but getting a new facility on sky ... that's hard to top! www.aip.de/en/news/4mos...

site visit at the ELT - it is taking shape!

The nice thing about LATAM airlines is that they are not afraid of having seat row #13.

Abell 262 is a galaxy cluster with some 100 members in the constellation of Andromeda, near the border to Triangulum. It is part of the Pisces-Perseus-supercluster. At the center is the cD galaxy NGC708. bit.ly/4lB3t… 🔭#astrophotography🔭📷

van den Bergh 140 is a blue reflection nebula in the constellation Cepheus. Adjacent is a large molecular cloud complex which makes the area around vdB140 a quite colorful region with blue, red and yellow tones. bit.ly/4lB3t68 🔭#astrophotography🔭📷

M110, aka NGC205, has a "wallflower existence" in Messier's famous catalogue. Although originally observed by Charles Messier in 1773, it never made it to his catalogue until it was added as its last entry not earlier than 1966! bit.ly/4lB3t…🔭#astrophotography🔭📷

vdB 133 is a reflection nebula powered by the yellow supergiant 44 Cygni. Its warm color makes the nebula appear white rather than the blue of reflection nebula powered by hotter stars. Adjacent is the large HII region LBN219. bit.ly/4lB3t68 🔭#astrophotography🔭📷

Moon, the day after …

eclipse!

The NGC 70 group, aka VV166 or Arp 113 is a quite appealing object. It shows galaxies of various morphologies and the mutual proximity triggers bar instabilities, deformations and lots of tidal debris. bit.ly/4lB3t68 🔭#astrophotography🔭📷

There is a tongue-in-cheek unit of volume called the Hubble-barn, equal to the volume of a cylinder with cross-sectional area of one barn (100 fm^2 - about the size of a uranium nucleus) and height of one Hubble length (14.4 billion light years). It works out to three and a half gallons.

M81 a.k.a. Bode's galaxy. Interestingly, this galaxy has two types of dust features - the more circular ones are part of M81, while the (fainter) straight lines as absorption features caused by our very own Milky Way bit.ly/4lB3t68 🔭#astrophotography🔭📷

How would the fireworks galaxy NGC6946 look like if it would not be located close to the Galactic plane? I estimated the reddening using a Schlegel&Finkbeiner dust map, the further process is as similar as possible to the original. bit.ly/4lB3t68 🔭#astrophotography🔭📷

The famous summer object NGC7000, a.k.a. the Northamerica nebula, using Sii guilded HOO rather than SHO. This palette give a more red-blue dominant HOO-like look with areas of considerable Sii emission being orange-yellow. bit.ly/4lB3t68 🔭#astrophotography🔭📷

NGC1499, the California nebula, is a HII region in Perseus discovered by Edward Barnard in 1885. It extends for more than 2.5° on the sky and is a frequently targeted object for wider field setups. bit.ly/4lB3t68 🔭#astrophotography🔭📷
