Ein Tagesausflug zum Hohen Venn in Ostbelgien, in der Nähe von Baraque Michel und Mont Rigi. Eine gute Gelegenheit, neues Sony-Equipment zu testen. ;-)
A 2 panel mosaic of SHO data in Sagittarius, the reflection nebulae NGC 6589/90 and Surroundings, in particular the emission nebulae IC 1283 und IC 1284. NGC 6590 also seems to be cataloged as NGC 6595.
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.
