Hi Brett,
Welcome!
While you could use the "Custom Catalog" feature for creating an observation list, the original intent behind Custom Catalogs is to be able to add objects missing from the pre-bundled catalogs.
I am planning to add proper support for Observing plans / lists, so that you could:
- see these objects prominently in the what's-up-tonight section
- see best times for viewing these objects from your location
- jot observation notes for the objects
- share these lists with others
