Abell 1656 is a big cluster of galaxies. The symbol for this object is a five sided
figure about 4 degrees across. The Zwicky cluster 5619 is a smaller (similar
looking) five sided grouping inside the Abell cluster group. There are many Zwicky
clusters in the area. If you see the label for any of these, right click on the
label and a box will appear to change the settings.

Try entering 5582 in the Zwicky box or 1641 in the Abell box and some much smaller
nearby clusters will be centred.
