Actually, it appears he may not be.

This page on the NGC/IC website:


"The data of my Revised New General Catalogue and Index Catalogue are
used by Mathematica, TheSky, Guide, SkyMapPro, Starry Night,
Eye&Telescope, the SAC database and the database of the Losmandy

If as this claims SAC contains data from NGC/IC then SAC would be
required to follow the license terms of NGC/IC, and the person running
SAC cannot relicense that data without the permission of NGC/IC.

we get:

"Any non-commercial use of my data is free! If a commercial use is
planned, please contact me!"

This would appear to make it impossible to include NGC/IC in Fedora,
and that would also apply to any derivative works like SAC.

[Note that Sky & Telescope also appears to use this data, which may be
an indication as to why they are unable to relicense their product]
