This adds the HD 167128 system which was recently discovered to host to stars and the closest black hole to Earth.
Note: Due to this being recent, the orbits are poorly constrained and the outer star's orbital period is unknown. See article below for further info.

Good but :
- QV Telescopii is a hierarchical triple
- QV Tel Aa and QV Tel Ab, black hole are a binary system
- this first binary and QV Tel B are a second binary system
There should be 2 barycenters
In Celestia HD 167128 is defined as star HIP 69605:HD 167128:SAO 245369
It is certainly necessary to complete "starnames.dat":
69605: QV Telescopii
this avoids the file "QV Telescopii 1.stc"
what is your opinion ?

When looking through the data, I didn't much of anything for QV Tel B other then its orbit is unconstrained.

I understand. This will certainly evolve in the future. Your work is already a good foundation.
well done

When updated I'll condense the STCs down, but the reason why I have the QV Telescopii 1.stc file is due to naming the barycenter (even with the numbers in front of Barycenter) "QV Telescopii" program refuses to load the barycenter.

QV Telescopii is also :
HIP 89605
HD 167128
SAO 245369
These 3 names are already in the Celestia base files
Do not add 89605 to starnames.dat
modify in QV Telescopii 2.stc
Barycenter 89605 "QV Telescopii:QV Tel:HR 6819" # HIP 89605:HD 167128:SAO 245369
QV Telescopii 1.stc is no longer required
Added after 1 hour 15 minutes:new texture for the black hole QV Telescopii
(your texture in Super Massive Black Hole)
Advantage: we see it spinning

i prefer black holes being black
