Thanks for the link - It looks a great site. Actually, it is an Astrological resource because I think we should look at maps such as these so that we get a clearer idea of what a horoscope chart actually shows.
The sky view, the horizon view and the data tables are all great tools for increasing our understanding of the sky -- even for those of us who learned to cast charts by hand using logs and tables/books (that seems so ancient and 50ish). Thanks for posting this, I've put in my favorites listing. Dave
