When selecting objects within Planner, you can filter using a catalogue name or abbreviation, e.g. "NGC"
Likewise when doing an object search, you can enter the catalogue name or abbreviation and it will return all objects that have a designation within that catalogue.
But I can't find a list anywhere of what those actual catalogue names and abbreviations are.
(1) Does such a list exist?
(2) Suggestion: the functionailty would be better if you could select from a drop-down list rather than enter (unvalidated) strings with separators.
