The NST (New STar) Cluster is a 500x500x500 ly cube of stars, located 50,000 ly above the galactic plane of the Milky Way (it shouldn't clash with any existing real or proc-gen stars out there). The screenshot above shows the stars with a limiting magnitude of 15.00 so you can see most of them. Installation instructions are at the end of this post.
The Cluster itself is consists of 244,589 solo star systems, containing a total of 638,318 planets and 22,046 asteroid belts (represented by a single asteroid here, adding more asteroids in the belts would have really killed the loading time!). There are white dwarfs, neutron stars and a stellar-mass Black Hole, and most other star classes and types are represented. My program can generate the stars for multiple systems (but not the planets) and I've figured out a way to add binary systems and may add more complex systems later on - however if I do then that would change all the existing planets (they have randomised elements filling some of the gaps in the conversion code that would be regenerated) - so be warned that subsequent updates will change the Cluster! Also there are no moons since the star solver doesn't generate them for imported planets (I may be able to figure out a way to add those later).
Here's a sample system from the text output:

There are seven worlds orbiting a 4.371 billion year old F7 V star in this system - four rocky planets, and three gas giants. The third and fourth planet are both ringed habitable worlds with water on their surfaces, and the fifth and sixth planets are gas giants that are more massive than Jupiter. And this is what the inner habitable planet looks like:
The SE Star Solver calculates some extra things like tidal heating and greenhouse effect (and rings) so the temperatures are sometimes different to what I calculated, which means there might be a few odd worlds (e.g. that have water on their surface but should be too hot to allow that to exist). I also added things like a hydrosphere and pre-set atmosphere for the habitable planets during the conversion process.
Have fun exploring the cluster, and let me know if you find anything interesting! And thanks to everyone here and on the discord who has helped me get this up and running!
INSTALLATION: To install the NST Cluster add-on, download this file: NSTCluster Pak file
and then put that in your Steam\steamapps\common\SpaceEngine\addons\catalogs folder (which will be wherever steam is installed on your machine - you may need to create the addons/catalogs folder manually). If you want to try it on an older/non-steam version of SE then you can put it in your SpaceEngine\addons\catalogs folder - but be warned that I haven't tested it on older versions though.
NOTE: The add-on takes 1-2 minutes to load on my machine, but it uses about 14 GB of RAM (I have a NVIDIA GeForce 980 Ti 6GB video card) so you will need a relatively beefy machine to run it. I've only tried this on the steam version of SE (0.990) but it seems to work there.
Version1: Solo stars only
11Feb2020 am: Updated the pak file to fix eccentricity and class errors.
11Feb2020 pm: Updated the pak file to fix ocean height errors. Now it only takes a minute or so to load!
12Feb2020 am: Updated the pak file to fix a few minor issues (implemented neutron stars/black hole properly, fixed some incorrectly zeroed ages).
17Feb2020 pm: HUGE UPDATE - replaced pak file with a new version of the Cluster that now includes Binary Systems (the stars/orbital configuration generated by my code, with worlds placed by me but generated by SpaceEngine), life, and many other small tweaks. The download is now 45MB and requires about 14 GB RAM (still only takes a minute to load though).
