New General Catalogue DatabaseHaving produced scripts for several short talks on observing deep-sky objects it became increasingly frustrating when having noted key objects in a given constellation I kept noticing more interesting ones after the talk! There was only one thing for it; to take the bull by the horns and produce an NGC Database which would display all the NGC objects in any selected constellation at the push of a button. The NGC objects included in Stellarium go up to NGC 7840 however many of the NGC objects up to this one are missing. Of the ones that are given, some are listed as different objects in other reference sources, some are duplicates and even the actual existence is disputed in some cases. That is the trouble when “New” is included in a title; it does not stay new for very long. It turns out that 7216 NGC objects are listed on Stellarium. That is to say, 624 NGC objects are not included in Stellarium. The following file highlights some of the duplicates but to go through all the missing NGC objects explaining their absence would be a project in itself.Click the icon to view the file.NGC DuplicatesNGC Object Type The following file shows the number of NGC objects of a particular type which are included in Stellarium.
