I'll have to read through that thread a few times because it hasn't hit me as to what to do. I wonder if someone could simplify the process with a generic step by step procedure without a bunch of comments. Anyway, wouldn't it be as simple as setting the declination as usual and then adjust the elevation rod to get the right angle to true south? The offset for the GEOSATpro 1.2M is 27.3 degrees - since the prime focus antenna for my area is set about 42 degrees does that mean that I should set the elevation rod to give 14.7 degrees instead of 42? This is a bit confusing when comparing the use with an HH90 which has a latitude adjustment on the motor and then an elevation adjustment on the dish but no declination adjustment.
