Lacked info for some real stars:
GHJ2008 3
GHJ2008 3 (also know as XTE J1650-500) is a binary system located 26 000 light years from Sol in the constellation of Ara. It was firstly observed in the beginning of 21st century and registered as transient binary X-ray source. The black hole was claimed to have a mass of 3.8 solar masses, which back then made it the lightest ever found black hole. Later the claim was retracted and the approximations were about 5–10 solar masses. Years later detailed system scan revealed that first calculations were right and black hole has a 3.8 solar masses. For now the system also contains a K-class star that will likely be absorbed by the black hole in the next several hundred years.

P.S. Though the star is shown as a main body, you actually jump to the hole. Don`t know if it is a bug or intentional feature, so i decided not to include it in the system description
GRS 1730-312
GRS 1730-312 was firstly detected more than a millennium ago in 1994 with GRANAT orbital
observatory and Kvant module of the first multi-module space station Mir. It rapidly became
the most intensive X-ray source in the galactic center region and lasted in this state
for more than a month. After the end of the observation it was concluded to be a soft X-ray
transient which was caused by accretion of ordinary star by either a black hole or a
neutron star.
Nowadays the system hosts 4 black holes: B, C, D could be remnants of the devoured stars in
the past and the central A could be the devour because of its 150 solar masses which is three
times higher than second most massive black hole in the system.
P.S. I was too far away when I noticed the lack of info, so I think that some more photos are stiil needed.

GRS 1758-258
GRS 1758-258 was the first microquasar with winged radio features found in early 21-st century. At those times it
was observed at the 6 cm wavelength using the legendary VLA radio telescopes complex. The observation showed two jets that
made a Z-type morphology and indicated the microquasar as strong X-ray emitter, also capturing another unrelated source.
Data analysis revealed that system hosts a non-degenerate star and possibly one black hole.
Years later the system was firstly visited and scanned by CMDR GLYN-IE. The interesting thing is that nowadays it
contains two black holes and a neutron star, and as there is no supernova remnants around the place it was either
incorrect observation and assumption or relatively quick supernova cycle or one more black hole was later captured by
the system gravity. In any of the cases, it is a mystery to reveal for the modern scientist.

V821 Arae
V821 Arae (also referred as GX 339-4 and GRS 1009-45) is a moderately strong variable galactic low-mass X-ray binary source that contains a black-hole and G-class white-yellow star. System was firstly observed in 21st century and helped astronomers of those times in understanding black holes variable accretion disks. The system is a regular X-ray emitter because of the stellar matter, that flows from the star to the black hole and forms a disk around the latter. A strong variable relativistic jet is also usually observed. System holds only one ice world planet that regularly witnesses dances of the black hole and the star.

P.S. I also have some photos with a ship in the foreground but I do not think they are actually needed.
P.P.S. I actually used various sources to make more content descriptions, and the presented ones are the most informative that can be added to the entry for those who are interested. And, yes, the most content paper about GRS 1730-312 seems to be in Russian only , so if you manage to find a translation or some other article it would be really nice.
