The NGC/IC Historical Project

The NGC/IC Project is a joint amateur/professional effort to re-examine the 100 to 200 year-old source material used by John Dreyer to compile the NGC catalogue in 1888. A staggering 15-20% of all NGC entries have problems due to poor positions, misidentifications, duplicate entries and incorrect classifications. Some of these mysteries have created a maze of confusion in professional databases and amateur software. The project's sleuthing has resulted in recovering literally hundreds of mistaken or lost NGC and IC identities.  Steve will discuss the project’s results and the final compilation of a historically accurate NGC/IC.
