[QUOTE="a33, post: 1162074, member: 332642"] I am still not sure what you mean with centre of the dish. As you are talking about the faded elevation scales: Do you wish to find the angle of the dish face against the earth surface? Then the picture on this webpage might help: [URL="https://www.satellite-calculations.com/Satellite/lookinfo.htm"]Antenna Look Angles Info[/URL] You can see the elevation angle of the satellite against the horizontal, and also the declination angle of the dish face from horizontal plane. Declination angle of dish face = 90 - satellite elevation angle. This, of course, is a prime focus dish in the picture. For an offset dish, the angle for the dish face must be corrected for the offset angle. (The fact that also other angles, for a motorized setup, are shown in the picture, is not relevant for the dish angles.) Greetz, A33 [/QUOTE]
