Pentangles

Lawrence Jan 27, 2012

I am wanting to create some star charts in a simplified form for use in
a daily newspaper column but by chance the moon has arrived in front of
a feature marked by a large pentangle. It might be a Zwicky (?) region,
judging by the Zw label on identical nearby pentangles. I have not
found a way to switch these off. Advice most welcome.
