| DETAILS | NGC1600 is an elliptical galaxy and NGC 1601 is an edge-on spiral. NGC 1603 is probably an elliptical galaxy. NGC1606 is a weakly barred spiral. 2MASXi J0431266-045955 is an Infra-Red Source. A number of 2MASX objects are included in the rollover but have no data and therefore do not appear on this page. |
