Stellarium's magnitude should be different from the human eye (apparent magnitude).

Norton's Star and Reference Handbook: magnitude of M88 is 9.5 magnitude of M91 is 10.2

this is stellarium 0.12.9   

The magnitude of old version is more similar to what the eye sees. V-magnitude should not be equated to apparent magnitude

Is it possible to use OPENNGC instead of data from NGC objects in the Stellarium catalog? It seems more accurate than the default database.
