The attached pdf file gives data for most of the NGC objects in this thread.
It lists 422 NGC objects - all the NGC globular clusters, all the NGC nebulae and all the NGC planetary nebulae. It also lists galaxies to mag 10.
Open clusters, LMC and SMC objects are not included. (33 objects are north of dec +50 and 47 are south of dec -50)
The data is based on Dr. Wolfgang Steinicke's work.
