@DrBard yep that's basiscally it. BTW there's actually another app that does specific sun and moon calcs which you might want to look at also: https://banglejs.com/apps/#astroc
I'm not getting correct metrics from that app though but again I think it's just because of the acos issue; I've actually found a better function for that now than the one I gave before (Don't know what voodoo magic they do to work these out!): https://developer.download.nvidia.com/cg/acos.html
