If you go to the site and select Limerick as your site, it puts you somewhere in wicklow, a small bug there :oops:
Interesting, I wronte some co-ordinate software a while back and had a bug that put limerick on the east also! Wonder what their excuse is.
Anyway, find your co-ordinates on
www.maporama.com/share/
and enter then in calsky. The co-ord system is WGS84.
