That is undoubtedly correct.
Unfortunately, we don't know what the title of this MS is, nor any shelfmark of any copy, and I have not been able to find anything using Google searches.
The books that @nablator and I found have the same text as the Prague MS You are not allowed to view links. Register or Login to view. "Textus astronomici (1400-1450)", but that is not the same.
The claim of @BessAgritianin remains to be confirmed.
