found this video about finding solid dish focal point. Its in Hindi but you get the idea. FF to 7:20 minutes. i gave it a fast try, it should work. opinions/ideas/suggestions..
After a few days of clouds, i gave it a try and it does focus the sun on the LNB.
I only speak english. yes he does show you, if not in this one he has anther on where he put mirrors along the perimeter and show with a cardboard to get a nice tight circle not skewed in any direction.
Come to think of it further:
Just a white spot on your LNB doesn't mean you have "the" focal point, though.
Does the film mention this?
If the LNB is positioned too high or too low, you'd also get a big white spot on your LNB, but at a wrong offset angle.
You'd have to find the place where the dot is as sharp and as little possible, changeing both the dish elevation and the offset angle for the LNB.
Not really an easy procedure...
