I have been moping about this response for a while in quiet, because I enjoy both the Astronomer LTW and this mod and didn't want to live without either.
So I decided to do the fiddling myself.

I did not make changes to the Logic skill influence as Severino did it in the exact same way.
I also left the star/planet limit untouched because it's not too realistic anyway. Yes, the universe is vast, but you simply can't discover everything with just a wobbly telescope at home. :p
So in the end, I was only left with randomising the amount of money for each new discovery and make sure the notification showed up correctly, and that was fairly simple to do (and make tunable just like the original). So here's an add-on for the mod, for all those interested! Must load after lamare_LTW_Astronomer. Default money values are the same as in Severino's mod (stars §200-§1000, planets §300-§1,500). Introduces a new BCON 0x2006 in the TelescopeGlobals.

EDIT (2023-10-02) to fix a bug so then the correct given amount of money is also displayed in the discovery notification. Re-download if you want it fixed, but it's not a must. I guarantee that the amount given out is, indeed, random either way.
