Gaia BH1 Starfield in Ophiuchus – LRGB v1Gaia BH2 Starfield in Centaurus – LRGB v1Gaia BH3 Starfield in Aquila – LRGB v1
With #3 recently discovered in the analysis during preparation of Gaia DR4 data, there are now 3 black holes in the Gaia catalog. Or more precise, 3 binary systems consisting of a companion star and a likely stellar-mass black hole.
Regarding the BH3 image, at first I wasn’t sure whether I found the right object, as the catalog gives the coordinates RA=19h39m18.7115472s, DEC=+14d55m54.010992s and the read-out in Pixinsight showed ICRS RA=19h39m18.68s, DEC=+14d55m50.3s. But thanks to the discussion with Ulrich Bastian I found out that it is necessary to take into account the large proper motion of the object, which results in almost 4″ deviation in declination. Calculating the current position for 2024.5 with Astropy yields RA=19h39m18.66368537s DEC=+14d55m50.2085012s.
Almost exactly 10 years ago, I photographed the magnificient Pavo Galaxy with the IAS 20 inch AK3, my first object with such a “big scope”. Here’s the result of June 2024, with much more exposure time on the very same telescope. I originally planned to use my QHY268M with the AK3, but this camera is now used at the new IAS remote telescope. So back to the roots with a ASI294MC Pro one-shot-color camera.
NGC 5139 – Omega Centauri Globular Cluster – LRGB v1
The first light of the new IAS remote telescope at Hakos, Namibia. NGC 5139 aka Omega Centauri, the most massive known globular cluster in the Milky Way.
IC 4628 – Emission Nebula in Scorpius – SHO w/RGB stars v1
“Second” light of the new IAS remote telescope at Hakos, Namibia, featuring IC 4628, the Prawn Nebula in Scorpius. (Actually taken while on-site in June. ;-)

Von Baum zu Baum: Stadtteilspaziergang mit Kunst, Literatur, Musik, Tanz und Zauberei am 10. Mai 2024 durch Dellbrück (mit einem kleinen Abstecher nach Bergisch Gladbach).
You don’t get this often: colorful aurora at 51° latitude, north-east of Cologne, Germany. A strong solar storm is currently impacting Earth.
Das sieht man auch nicht alle Tage: Polarlichter in allen Farben über den ganzen Himmel bei heimischer 51° Breite, nordöstlich von Köln. Ein massiver Sonnensturm trifft gerade auf die Erde.
Spaziergang durch das Naturschutzgebiet Mutzbach im Norden von Dellbrück an der Grenze zu Bergisch Gladbach. Dieser wichtige Wegweiser soll offensichtlich Motoristen und Wanderer wieder auf den richtigen Pfad bringen.
