The software is called “Where is M13?”
By default. only Messiers are listed but go to the filter menu options to show all other catalogue items such as NGCs, Caldwell, Bayer stars etc. If you show all catalogues then show all objects, it gives a nice view of all the objects’ locations from a universal or galactical view. Explore the menu for presets such as constellation sectors etc.
