I made three modifications to the 8.0 version of the above code:

To get a more precise label for the observatory, I added 135 to MapX and 52 to MapY

var MapX = (Math.round(-2+((Telescope.SiteLongitude+180)*(720/360)))) + 135;
var MapY = (Math.round(20+(((Telescope.SiteLatitude*-1)+90)*(360/180)))) + 52;

Updated the timeanddate.com URL to:


This gives the above pictured "satellite view" instead of simple line graph.
