"simbad" is a catalog of catalogs with a built in web based search engine. It is pretty much what "everyone" uses to search. You can define a shape and ask for all objects that meet some criteria that are within that shape. Other software can plot the result for you as a chart If it is not in Simbad you have likely discovered something new.
