Satellite TV dish pointing in Canada

I've just been modifying my calculator page at
https://www.satsig.net/maps/satellite-tv-dish-pointing-canada.htm

It should now include a view of the earth as seen from the satellite. The page works for me but I would be interested to know if others can make the page work with different browsers and coming from different IP addresses.

The image comes after some delay as the calculations to replot the coastline take about 10 seconds of CPU run time on the computer under my desk. The output is a small blue gif file. You can see similar satellite views from a random viewpoint (i.e. not just on the geo orbit) if you look at the lower right hand side of page https://www.satsig.net/lat_long.htm

My next project is to draw a red line from your earth station site to the sub satellite point as this will give a good indication of the azimuth direction.

Best regards, Eric.
