The Filters Menu is used to choose which objects in the database are displayed in the Object Table.
By choosing an item in the Filters Menu you toggle whether that class of object or object catalog is displayed. Note that the object's type and the catalog must both be checked in order for it to be displayed. For example, to see the Bayer Stars, you must have both the Stars category and the Bayer Stars catalog checked. To see all the globular clusters in Messier catalog, check only Globular Clusters and Messier.
Shows the Filters Dialog, allowing your to make multiple changes to the objects and catalogs that are to be displayed.
