This is a work in progress. It's a database of common astronomical objects, designed to be used as a convenient teaching aid as well as for general reference. I originally started it because I wanted a handy way to look up objects when I'm doing telescope viewing evenings, so by default it's styled for mobile devices. I'm working on adding other styles for desktop viewing.
The database currently contains about 500 astronomical objects, although I haven't yet added many to the index. That's a very small database in astronomical terms but in a way that's the point—it's supposed to be a manageable database of things you're likely to want to know about, rather than a list of thousands of obscure objects.
