The CDS Portal#

You can start your search for astronomical objects by going to the CDS Portal (http://cdsportal.u-strasbg.fr). Here you can search for an object by name or position. The Sesame name resolver is used for search by name. Coordinates can be entered in HMS DMS format (17 57 48 +04 41 36) or decimal degrees (269.4500 +4.6933).
